In the present case, water-carrying lines are understood as meaning those lines which run in a building wall and supply or discharge water from the sanitary fitting which is finally installed. It may thus be a cold water, a hot water or mixed water mains.

When installing sanitary facilities, an end user should remain free for as long as possible, for example, if he has a single-lever mixing valve, a multi-way valve or a thermostatic mixer installed. For this purpose, it is known to assign sets of valves of different types of function a universal mounting device. This is inserted into an opening in a building wall and connected to the water-bearing house lines. The mounting device serves to receive a connection device of the set finally selected sanitary fitting and connects it to the house lines.

In the connection device of the sanitary fitting may be a fitting housing, in which in turn the cartridge of a selected sanitary fitting is used. It is also possible that the cartridge itself is inserted directly into the mounting device and forms the connection device of the sanitary fitting. Likewise, an adapter can serve as a connection device of the sanitary fitting, which connects the mounting device with the cartridge, as z. B. in the DE 196 22 368 A1 is disclosed, wherein there is used a mounting device of the type mentioned.

The installation device for sanitary fittings described therein comprises connections between the connection openings of the sanitary fitting and a cold water inlet, a hot water inlet and two mixed water drains. The compounds are formed as channels in the housing of the mounting device and thus permanently connected to the mounting device. This installation device is a relatively heavy metal body whose inner water-carrying channels require a rather complicated manufacturing process.

Various fitting devices of sanitary fittings suitable for an installation device can have a different number of connection openings. Thus, the connection device of a bathtub fitting connection openings for a cold water inlet, have a hot water inlet and two mixed water drains. From the latter one leads, for example, to the tub outlet of the fitting and the other to a shower.

By contrast, the connection device of another fitting can only have one connection opening for only one mixed water outlet.

The fitting for both connection devices mounting device of DE 196 22 368 A1 but can be adapted to these only by a non-required mixing water drain is closed by a stopper. This means, first of all, that the installation device is produced uniformly with always the same, sometimes unnecessarily large material consumption. In addition, it leads to further material requirements and higher costs when an unnecessary connection must be closed by a blind plug.

Otherwise, various mounting device would have to be produced, which is quite costly and contrary to the idea of a unitary for as many applications installation device.

From the DE 33 27 829 A1 an installation device is known in which a sanitary fitting is clamped between lateral metal flanges, which connect at the same time inlet and outlet pipes to the side connection openings of the sanitary fitting.

Object of the present invention is to provide a mounting device for sanitary fittings of the type mentioned, which is suitable for different sanitary fittings, material saving and low in the production.

This is achieved by an installation device according to claim 1.

According to the invention this is achieved in particular by the fact that at least one connecting means is a separate part from the housing and is optionally insertable into the housing.

This ensures that the installation device can be adapted to different sanitary fittings with a different number of connection openings, since only as many connection means as necessary must be used. This consequently leads to a saving of material, since there is no material surplus. Also, an additional plug for closing an unnecessary connection means of the mounting device does not fall at. In addition, the production of small items is cheaper than the production of solid components with a complicated internal structure, as is common in known mounting devices.

The design of the connecting means as a connecting piece ensures that the connecting means have a geometrically relatively simple shape. Such connecting pieces are quite simple and inexpensive to manufacture.

Characterized in that the connection piece is inserted through housing openings in the outer wall of the housing so far into this, that the connection opening of the connection piece inside the housing and the fastening means of the connecting piece outside the housing, it is ensured that the connections of the connection piece are positioned so as required during assembly of the mounting device.

The measure according to claim 2 allows the optional connection of up to four house lines to the mounting device, which in turn is adaptable to many sanitary fittings.

Due to the design of the connection piece according to claim 3, these are adaptable to specific installation requirements.

It is advantageous if the connection piece according to claim 4 are made of plastic, since the connection piece so z. B. can be produced by injection molding.

In order to achieve a sufficient attachment of a connection piece on the housing, it is advantageous to fix this according to claim 5 within the housing by a guide element.

The manufacture of the mounting device is further simplified and thus more favorable when the guide element, as described in claim 6, is part of an attachable in the housing holding device.

The fixation of the connecting piece takes place in a very simple manner, if this and the guide element are configured according to claim 7.

The connection device of the sanitary fitting is easy to use in the mounting device when a fastening and guiding device according to claim 8 is provided, which leads the connecting device radially.

It is cost and production technology advantageous if the fastening and guiding device according to claim 9 is arranged on the holding device.

A favorable measure is to form the holding device according to claim 10 as a holding plate.

It is advantageous if the holding plate according to claim 11 consists of a thin sheet metal. The holding plate is to produce by punching in a fairly simple manner.

An alternative measure is to form the holding device according to claim 12 as a holding pot.

It is inexpensive if this is a molded part made of plastic according to claim 13.

In order to secure the connecting piece in the housing, it is advantageous to provide a fixing device according to claim 14, which fixes the connecting piece radially against withdrawal.

The installation and removal is facilitated if the holding device according to claim 15 is releasably fixed by at least one fastener.

It is material-saving, if the fixing device according to claim 16 by the fastening element, which also fixes the holding device, is releasably secured in the housing.

The fact that a mounting plug is provided according to claim 20, it is achieved that the connecting pieces are fixed during assembly and the house lines can be checked for leaks in a known manner.

It is advantageous if the assembly plug according to claim 21 is releasably attachable to the support plate.

The mounting plug can be produced inexpensively if it is according to claim 22 made of plastic.

By the measure according to claim 23, the Einbauvorrrichtung can be used at different mounting depths in the building wall. This takes into account the fact that the house wires do not run everywhere in the same depth in the building wall.

With an axial extent of at least 10 cm according to claim 26 this is ensured for common installation depths of the mounting device in installation openings in building walls in general.

The separation of the protruding from the opening of the building wall part of the housing is to perform well when the housing according to claim 27 made of plastic. Moreover, it is so easy and inexpensive to produce.

Furthermore, the use of plastic leads to a low weight of the housing, which is advantageous in the installation.

The FIG. 1 shows an installation device 1 for sanitary mixing fittings. The mounting device 1 comprises a cup-shaped housing 10 made of plastic with a cylindrical peripheral wall 12 and a rear wall 14. On the side remote from the rear wall 14, the housing 10 has an opening 16. The wall thickness of the cylindrical peripheral wall 12 increases from the opening 16 in the direction of the rear wall 14.

In the vicinity of the rear wall 14, the housing 10 is provided with four housing openings in the form of stepped holes 18, which along the circumference of the peripheral wall 12 in each case 90 ° are arranged offset.

In the housing 10 is in the amount of stepped holes 18, a holding device, which is designed as a holding plate 20 having a substantially octagonal base 21. The holding plate 20 is inserted into the housing 10 so that the stepped holes 18 in the outer cylindrical wall 12 each have a side edge of its base 21 opposite, but without being directly attached to the housing 10 itself. The holding plate 20 is made of thin sheet metal.

At each of the four side holes of the base 21 facing the stepped bores 18, a fastening and guiding device 22 is arranged, which serves for fastening and radial guidance of the connecting device, not shown, of a sanitary mixing fitting. A perpendicular to the base 21 of the holding plate 20 extending portion 24 is to each radially inwardly bent to a portion 26 which terminates in an arcuate edge 28.

As in FIG. 3 can be seen, the sections 26 of the guide means 22 are not parallel to the base 21 of the holding plate 20, but obliquely to this.

The sections 24 of the guide means 22 have an arcuate recess 29 whose diameter corresponds approximately to the smaller diameter of the stepped bore 18 in the housing 10 and in any case is so large that a portion of a below-described connecting piece 40 through the recess 29 is feasible.

The base 21 of the holding plate 20 has four recesses 32, each of which faces the stepped bores 18 Side edges of the base 21 extend radially inwardly, thereby connect to the recesses 29 of the sections 24 and terminate in a semicircular edge 34. The width of the recess 32 and thus the diameter of the semicircular edge 34 is smaller than the smaller diameter of the stepped bore 18th

The edges of the recesses 32 together form respective guide elements 30, each of which serves to receive a subsequently explained connection piece 40.

In the middle of the base 21, the holding plate has a threaded bore 36.

In FIG. 1 four identical connecting pieces 40 are shown, two of which are outside the housing 10 and two are introduced through the stepped holes 18 in the housing 10.

A central portion 42 of such a connecting piece 40 merges at one end into an approximately 44 ° angled portion 44 and at the opposite end in a step portion 50 on. At the step portion 50, a mounting hexagon 52 is attached, by means of which a building-side water-bearing pipe (not shown) is attached to the connecting piece 40. The fastening hexagon 52 has a threaded bore 54 for this purpose.

As in FIG. 3 can be seen, extending through the step portion 50 and the central portion 42 of the connecting piece 40 axially a water-conducting passage 46 which opens at its radially inner end into a connection opening 48 in the form of a stepped bore in the portion 44 of the connecting piece 40. The axis the connection opening 48 is perpendicular to the axis of the passage channel 46. At its other end, the passage 46 opens into the threaded bore 54 of the mounting hexagon 52nd

Starting from the step portion 50, the outer wall of the central portion 42 of the connecting piece 40 has two in the plane perpendicular to the axis of the connection opening 48 in the portion 44 of the connecting piece 40 opposite parallel groove portions 56a, 56b. These are connected by a further groove portion 56 c in the peripheral wall of the portion 44 of the connecting piece 40 to a single U-shaped groove 56. This is designed such that the connecting piece 40 with the groove portions 56a, 56b on the parallel edges of the recess 32 of the holding plate 20 is slidable. The connecting piece 40 thereby partially passes through the recess 29 of the corresponding fastening and guiding device 22.

If the connecting piece 40 is completely inserted into the recess 32 of the holding plate 20, the stepped portion 50 of the connecting piece 40 extends through the stepped bore 18. In the groove portion 56c each of the semicircular edge 34 of the recess 32 engages. A radial sealing of the thus introduced into the housing 10 connecting piece 40 is carried out in each case by not shown O-rings, which are inserted before the insertion of the connecting piece 40 in the stepped holes 18 of the housing 10. As a result, the connecting piece 40 is fixed in the axial and circumferential directions and abuts the stepped bore 18 via the mentioned O-ring.

The FIGS. 2 and 3 show the mounting device 1 with four inserted connection piece 40, wherein in the connection openings 48 of the connecting piece 40, a mounting plug 57 is inserted. The mounting plug 57 consists of a plate 58 which has four projections 59, which respectively fit into a connection opening 48 of the connecting piece 40. In the projections 59 is each a parallel to the plate 58 outside circumferential groove 60 which can accommodate an O-ring, not shown. As a result, the connection openings 48 of the connection piece 40 are sealed when the assembly plug 57 is inserted.

The plate 58 of the mounting plug 57 has a centrally disposed bore 61. The mounting plug 57 is fixed by means of a guided through the bore 61 screw 62 which engages in the threaded bore 36 of the support plate 20, releasably secured to the support plate 20.

Before installing the mounting device 1 is usually known which basic type of sanitary fitting to be installed after the shell assembly. If this is e.g. to a bathtub fitting, so their associated connection device usually four to be connected with water-carrying lines connections. These are each a connection for cold water inlet, one for hot water supply and two connections for a mixed water outlet. The two mixed water drains lead, for example, to the bath spout of the fitting or to a shower.

Therefore, prior to assembly of the mounting device 1 four connecting pieces 40 are inserted through the stepped holes 18 in the housing 10, wherein the connection openings 48 of the connecting piece 40 point in the direction of the opening 16 of the housing 10. The connecting pieces 40 are doing within the housing 10 through the arcuate recesses 29 of the support plate 20 and with the groove 56 in the guide elements 30 of the holding plate 20 is inserted until the arcuate edge 34 of the corresponding guide member 30 engages in the groove portion 56c of the connecting piece 40. The connecting pieces 40 can no longer rotate within the stepped bores 18 now.

The step portion 50 of the connecting piece 40 now extends through the respective stepped bore 18 of the housing 10th

After the connecting pieces 40 are inserted into the mounting device 1 in the manner described above, the mounting plug 57 is placed on the connection openings 48 of the connecting piece 40 and secured by means of the screw 62 to the support plate 20. This prevents that the connecting pieces 40 can slide in the radial direction of the housing 10. In addition, the ports 48 of the ports 40 are sealed by the above-mentioned O-rings in the grooves 60 of the projections 59 of the mounting plug 57. The pipeline system can then be tested in a known manner by pressing for leaks.

The holding plate 20 itself does not have to be fixed directly to the housing 10. The mutual interlocking of the individual components is sufficient to fix the components involved.

Now, the mounting device 1 is inserted into the wall opening and not shown here located in the building wall Wasserzu- and -ableitungen on the mounting hexagon edge 52, each with a connecting piece 40. The housing 10 of the mounting device 1 is to be fastened in the wall opening via known fastening means, which are not shown here.

The cylindrical peripheral wall 12 of the housing 10 has a relatively large axial extent, as in the FIGS. 1 and 3 can be seen. Thus, the mounting device 1 can be used at different mounting depths in the wall opening. When mounted in the wall opening mounting device 1 of the wall projecting portion of the cylindrical peripheral wall 12 is simply cut off, so that the resulting front edge of the housing 10 is aligned with the masonry, the tiles on the wall or the like.

Before installing the sanitary fitting, the screw 62 is released and the mounting plug 57 pulled out of the connection openings 48 of the connecting piece 40. In the free connection openings 48 of the connecting piece 40 now the connection openings having connection piece of the sanitary fitting are inserted. It is understood that the connecting piece of the connecting device for this purpose must be complementary to the connection openings 48 of the connecting piece 40 of the mounting device 1.

By the outer surface of the connecting device of the fitting corresponding embodiment of the arcuate edges 28 of the radially inwardly extending portions 26 of the holding plate 20, these serve as a guide of the connecting device of the mixing fitting by abutting the outer circumferential surface of the connecting device.

The radially inwardly extending portions 26 of the holding plate 20 also serve as part of a bayonet closure. For this purpose, the connecting device of the fitting has a rotatable sleeve with a corresponding axial distance from its connecting pieces arranged ribs which extend in the circumferential direction of the sleeve so far and are spaced apart from each other that they Inserting the connecting device in the housing 10 between the sections 26 are feasible. If the sleeve after insertion of the connecting piece of the fitting in the connection openings 48 of the connecting piece 40 is rotated in the circumferential direction, the ribs of the connecting device are clamped by the inclined portions 26 of the support plate 20 and pulled the connecting device of the valve in the direction of the holding plate 20.

If the connection device of a fitting to be installed does not have four connecting pieces 40, as assumed above, then the mounting device 1 can be correspondingly adapted to the connecting device before being mounted.

For example, another basic type of faucet, in contrast to the bathtub fitting described above, can only have a mixed water outlet. The associated connection device accordingly includes connections for a cold water inlet, a hot water inlet and a mixed water outlet. In the mounting device 1 so three connecting pieces 40 must be present in order to connect the connecting piece of the valve with the water-bearing house lines. In this case, only three connecting pieces 40 are inserted into the housing 10 according to the positions of the connecting pieces of the fitting as described above.

The further assembly of the mounting device 1 is carried out as described above. The mounting plug 57 also fits into the ports 48 of the ports 40 when fewer than four ports 40 are inserted into the housing 10.

The following is based on the FIGS. 4 to 7 a further embodiment of a mounting device for sanitary fittings described. In these, the embodiment of the FIGS. 1 to 3 in their function corresponding components with the same reference numerals plus 100.

The housing 110 has on its outer circumferential surface between the stepped holes 118 in the peripheral wall 112 four radial fastening eyes 63, which are aligned with the rear wall 114 of the housing 110. The radial fastening eyes 63 are each penetrated axially by a bore 64. In addition to the fastening eyes 63 are located in cylindrical thickenings of the peripheral wall 112 of the housing 110 blind holes 65, as shown in FIG. 5 can be seen.

By means of the fastening eyes 63 and / or the blind bores 65, the housing 110 can be fixed in an opening in the masonry.

The stepped bores 118 are first closed by a plate 66 after the production of the housing 110. The plate 66 is integrally connected to the inner circumferential surface of the smaller diameter portion of the stepped bore 118. The connection line 67 ( Fig. 4 ) is formed diluted, so that along the connecting line 67 of the plate 66 with the stepped bore 118 is a predetermined breaking point 67. Thus, as required, the plate 66 can be broken out of the stepped bore 118 when a connecting piece 140 is to be inserted through this into the housing 110.

One of the connecting pieces 140 of the FIG. 4 , which is designated by the reference numeral 140a, in contrast to the other connecting piece 40 of the FIGS. 1 to 3 in its central portion 142 has an opening 68. By the. Opening 68 are various functional elements, such as Vorabsperrventile or muffler (not shown), in the connecting piece 140a integrated.

The main difference of the installation device of FIGS. 4 to 7 to the embodiment of the FIGS. 1 to 3 consists in the manner in which the connecting pieces 140 are fixed in the housing 110.

The holding device is designed here as a holding pot 120. This has a circular base surface 121 and a cylindrical peripheral wall 124. The holding pot 120 is a molded part made of plastic or an extruded part made of metal.

The circumferential wall 124 of the holding pot 120 has circumferentially alternately four portions 69 of lesser wall thickness and four sections 70 with greater wall thickness, such that the inner circumferential surface of the peripheral wall 124 is alternately offset radially outward or inward and facing each two sections of the same wall thickness. Just below the opening of the holding pot 120 is located in the inner circumferential surface of the peripheral wall 124 has a circumferential groove 71st

Due to the embodiment described above, the circumferential wall 124 of the holding pot 120 has four radially inwardly projecting portions 126, which terminate in a circular-arc-shaped edge 128. This results in a fastening and guiding device 122, which like the fastening and guiding device 22 of the FIGS. 1 to 3 the attachment and radial guidance of a connecting device, not shown, a sanitary mixing fitting is used.

The peripheral wall 124 of the holding pot 120 has starting of its base 121 on four axial recesses 129, which are arranged in the portions 69 with a smaller wall thickness of the peripheral wall 124. The recesses 129 are corresponding to the recesses 29 of the embodiment of the FIGS. 1 to 3 in any case so large that a part of the connecting piece 140 is feasible through them.

The base area 121 of the holding pot 120 has four recesses 132, which each extend radially inwardly from the recesses 129 and terminate in a semicircular edge 134.

The parallel and semicircular edges 134 of the recesses 132 together form guide elements 130, via which the connecting pieces 140 are slidable by means of their grooves 156.

On the inner lateral surfaces of the four sections 70 with greater wall thickness of the holding pot 120 is in each case an axial rib 72. The ribs 72 extend from the base 121 of the holding pot 120 and terminate in a bearing surface 73. This is in the guide member 130 inserted connecting piece 140th slightly below the edge of the angled portion 144 of the connecting piece 140 facing away from the base 121 of the holding pot 120, as shown in FIG FIG. 7 can be seen. The ribs 72 with the support surfaces 73 serve as a support of a later to be explained fixing ring 86th

The base 121 of the holding pot 120 has two bores 74 on a diagonal between two ribs 72. One of them is in FIG. 7 to recognize. There is also one of two recesses 76 of the rear wall 114 of the housing 110 can be seen. The axially offset in the housing 110, parallel to the rear wall 114 of the housing 110 Inner wall 77 of the recess 76 each has a bore 79. The recesses 76 are arranged in the rear wall 114 of the housing 110, that their bores 79 are each coaxial with one of the holes 74 in the base 121 of the holding pot 120 when it is inserted into the housing 110 and aligned accordingly.

As FIG. 7 shows, the holding pot 120 is fixed in the housing 110 by a fastener 80, which is based on below FIG. 4a is explained in more detail.

The fastener 80 is made of elastic material and has a disc 81, two on the opposite circular surfaces of the disc 81 coaxially arranged cylinder sections 82 and coaxially thereafter each have a cone portion 83, which ends in a spherical element 85. The diameter of the cylinder sections 82 is smaller than the diameter of the disc 81. The conical sections 83 are each formed with their larger diameter end on the cylinder sections 82, wherein the larger diameter of the conical sections 83 between the diameter of the disc 81 and the diameter of the cylinder sections 82nd lies.

As in FIG. 7 can be seen, the inner wall 77 of the recess 76 on its side facing the opening 116 of the housing 112 side to its bore 79 coaxial recess 78. Complementarily, the base 121 of the holding pot 120 has on its outer side a recess 75 coaxial with its bore 74.

The diameters of the recesses 75 and 78 correspond to the diameter of the disc 81 of the fastening element 80. The diameter of the holes 74 in the base 121 of the holding pot 120 and the diameter the holes 79 of the recesses 76 correspond to the diameters of the cylinder portions 82 of the fastener 80. The diameter of the spherical elements 85 of the fastener 80 is slightly smaller than the diameter of the holes 74 and 79th

In FIG. 4 a cooperating with the holding pot 120 fixing ring 86 is shown. This consists of a ring member 87 having an outer diameter corresponding to that inner diameter of the holding pot 120, which is formed by its portions 70 with greater wall thickness. Radially outwardly on the ring member 87 of the fixing ring 86 are integrally formed four angled projections 88. These are designed so that a clear diameter of the fixing ring 86 is formed by their furthest outboard edge 89, which corresponds to that inner diameter of the holding pot 120, which is formed by the portions 69 of lesser wall thickness. The angled projections 88 have an extent in the circumferential direction, which is slightly smaller than that of the portions 69 of lesser wall thickness of the holding pot 120. The angled projections 88 are each offset by 90 ° to the ring member 87 of the fixing ring 86.

Overall, the fixing ring 86 is designed such that it can be inserted into the holding pot 120, wherein the angled projections 88 are in the portions of lesser wall thickness 69 of the holding pot 120, as shown in the Figures 5 and 6 can be seen.

The ring member 87 of the fixing ring 86 has an inner edge 90 which extends in alternating sections 91 with a small radius of curvature and portions 92 with a large radius of curvature. The radius of curvature of Sections 91 corresponds to the outer radius of the angled portion 144 of the connecting piece 140. The portions 91 with a small radius of curvature of the inner edge 90 of the ring member 87 are offset by 90 ° arranged so that they face the angled projections 88. Overall, the inner edge 90 of the ring member 87 is formed so that its sections 91 extend with inserted fixing ring 86 and inserted connecting piece 140 along the direction of the inner wall of the holding pot 120 facing outer surface of the angled portions 144 of the connecting piece 140. This is in the Figures 5 and 6 clearly visible.

Starting from the inner edge 90 of the ring element 87, the sections 92 with a large radius of curvature have a central centering recess 93. Around the recesses 93 around the ring member 87 recesses 94.

The installation of the mounting device of FIGS. 4 to 7 now happens as follows.

First, according to the required number and position of the connecting piece 140 plates 66 are broken out of the stepped holes 118 of the housing 110 along the predetermined breaking points 67. The fasteners 80 are guided through the opening 116 in the housing 110 and with their spherical elements 85 through a respective bore 79 of a recess 76. This is done without greater force initially so far that the edge 84 of the cone portion 83 of the fastener 80 is located on the side of the recess 78 of the inner wall 77 of the recess 76. Now, the fastener 80 is pulled from the back 114 of the housing 110 through the bore 79. If a train is exerted on the conical section 83 of the fastening element 80, then this lengthens Fastener 80 due to its elasticity axially, whereby the diameter of the edge 84 of the cone portion 83 is reduced and this can be pulled through the bore 79 therethrough. Then the disc 81 of the fastener 80 is located in the recess 78 of the inner wall 77 of the recess 76. The conical portion 83 of the fastener 80, however, abuts against the rear wall 114 of the housing 110 facing side of the inner wall 77 of the recess 76 at. Thus, the fastening element 80 is fixed.

The holding pot 120 is inserted through the opening 116 into the housing 110, wherein the recesses 129 in the peripheral wall 124 of the holding pot 120 point in the direction of the stepped holes 118. The holding pot 120 is now further inserted into the housing, so that the bores 74 are guided in its base 121 over the lying in the housing 110 spherical elements 85 of the fasteners 80. On the lying in the housing 110 cone portions 83 of the fasteners 80 as described above, a train is exercised, now the edges 84 of the cone portions 83, facing the opening 116 of the housing 110, reduce their diameter and through the holes 74 in the base 121 of the holding pot 120 penetrate. Thus, the discs 81 of the fasteners 80 are now in the recesses 75 of the base 121 of the holding pot 120. Overall, the holding pot 120 is now fixed axially and radially.

Now, the fixing ring 86 is inserted into the housing 110 and the holding pot 120. In this case, the angled projections 88 in the direction away from the rear wall 114 of the housing 110 direction. The fixing ring 86 is inserted into the holding pot 120 so that the angled projections 88 with the portions 69 of lesser wall thickness of Holding pot 120 aligned. The fixing ring 86 is inserted so far into the holding pot 120 until it comes to rest on the bearing surfaces 73 of the ribs 72 of the holding pot 120.

For this purpose, the conical portions 83 of the fasteners 80 must be radially bent slightly inwards so that they lie within the fixing ring 86. The axial extent of the conical sections 83 is selected so that now the spherical elements 85 abut against the inner edge 90 of the fixing ring 86. If the conical sections 83 are now axially elongated under a slight tension, they can be introduced laterally from the inside into the latching recesses 93 of the fixing ring 86. When strain relief, the spherical elements 85 of the fasteners 80 come to lie in the recesses 94 of the fixing ring 86. As a result, the fixing ring 86 is axially fixed, as in FIG. 7 can be seen.

Finally, the required connecting pieces 140 are inserted through the stepped holes 118 in the housing 110 until the step portion 150 of the connecting piece 140 extends through the corresponding stepped bore 118. A radial seal is again by not shown O-rings, which lie in the stepped holes 118.

During the insertion of the connecting piece 140 into the housing 110 whose angled portion 144 moves through the recess 129 in the peripheral wall 124 of the holding pot 120. In this case, the radially inner and facing the opening 116 of the housing 110 edge of the angled portion 144 abuts the connecting piece 140th each against an angled projection 88 of the fixing ring 86 and exerts thereon a force in the direction of the opening 116 of the housing 110.

Since the fastening elements 80, which hold the fixing ring 86 axially, are elastically deformable, the fixing ring 86 is attached as a whole tiltable. Thus, it can dodge the force applied to it in the direction of the opening 116 of the housing 110. After the connecting pieces 140 are completely inserted into the housing 110, the fixing ring 86 snaps back when the angled portions 144 of the connecting piece 140 reach behind the inner edge 90 of the fixing ring 86. Then, the portions 91 of the ring member 87 are located on the in the direction of the inner circumferential surface of the peripheral wall 112 of the housing 110 facing outer surface of the angled portions 144 of the connecting piece 140 and the connecting pieces 140 are fixed radially against withdrawal.

As with the mounting device 1 of FIGS. 1 to 3 the connecting pieces 140 are guided through the recess 129 of the peripheral wall 124 of the holding pot 120 so that they are pushed by their groove 156 on the respective guide member 130, whereby they are fixed axially and transversely.

All further and unspecified assembly steps here correspond to the procedure as they are based on the mounting device of FIGS. 1 to 3 has been described.
