With reference to FIGS . 7 and 8, preferred embodiments of the seal 5 according to the invention are described. Referring to FIG. 5, the seal 7, a pair of sealing lip 5 a, 5 b on. As far as the seal is described above in connection with Fig. 1 be, the same reference numerals are used and reference is made to the preceding description. Each sealing lip consists of two parts 21 , 22 as shown in Fig. 7 by corresponding reference numerals with respect to the sealing lip pe 5 b. The two parts are at least partially separated from one another by a dividing line or dividing surface 23 which is essentially transverse in FIG. 7. On the outward-facing surface of the sealing lips 5 a, 5 b, the two parts 21 , 22 are firmly connected to one another, with a tear-off edge designated 24 being provided at the height of the dividing surface or dividing line 23 . With this construction of a seal, it is possible to remove the entire lower part 22 from the upper part 21 , so that the seal 5 has only the upper part 21 available as a sealing lip. Thus, the above-described fastening device can be used with a seal 5 in the area of the transom, which only includes the upper part 21 , and can thus be placed on the sealing lip area of the seal in the area of the post, which, how, at intersection points between transom and post will be described hereinafter, has sealing lips that have only the lower part 22 . In other words, this means that in the area of crossings between transoms and posts, the sealing lips can each be cut to half the height, namely where the crossing takes place.

Furthermore, the seal 5 is provided with tear-off edges 26 , 27 which enable the removal of the bearing rib 14 a, 14 b in order to use the seal in a connection profile, as shown in FIG. 3. Here, the screw channel 2 has no laterally extending legs 2 a, 2 b so that the sealing lip 5 a, 5 b can be seated over the entire surface of the wall 1 a. The height of the legs 2 a, 2 b compensating ribs 14 a, 14 b are evidently not required or unfavorable in the embodiment according to FIG. 3. The separation edges 26, 27 are at the transition between the rib 14 a, 14 b and the seal lips 5 a, 5 b of the parts in height of the lower surface 22a designated 22, each lip 5 a and 5 b.

The seal 5 shown in Fig. 8 is intended for use on a post. As explained above, the upper part 21 of each sealing lip 5 a, 5 b is removed over a predetermined length in the intersection area with a bolt by means of between the upper part 21 and the lower part 22 in the region of the outwardly facing surfaces Tear edge 24 . The tear-off edge 24 is located on the laterally outwardly facing surfaces of the lips 5 a, 5 b at the level of the separating surface 23 .

Another tear-off edge is formed between the section 13 d and 13 b in the seal according to FIG. 8 and is characterized by 30 be.

The dividing line or dividing surface 23 between the upper and un lower part 21 , 22 can be formed in a zigzag shape, which ensures good adhesion between the upper and lower part 21 , 22 , even if the dividing line or dividing surface 23 according to FIG. 7 runs continuously between both parts until just before the tear-off edge 24 . Due to the profiled separating surface 23 , the lips 5 a, 5 b, that is to say the superimposed parts 21 , 22 avoid a displacement or displacement in the transverse direction when the lips are loaded.

The sealing parts 21 , 22 are substantially aligned in the longitudinal direction, as can be seen from FIGS . 1 ff. And preferably have approximately the same height.

In the embodiment according to FIG. 8, the two parts 21 , 22 are separated from one another by a separating surface which lies at the tear edge 24 ; in this respect, express reference is made to FIG. 8.

The two connecting sections 13 b, 13 g of the parts 22 and 21 of the seal according to FIG. 7 are brought together at the contact surface 25 and define a polygonal cavity 28 . Demzufol ge defined in the gasket 5 of FIG. 7, the portion 13 g of the water gutter, while the water drainage channel b defines with the gasket 5 of FIG. 8, the portion 13. In this way, as already mentioned above, the water drainage paths with respect to the transom are set at a higher level than with a seal 5 with respect to the post seal.

In order to be able to insert the seal 5 sufficiently firmly into the screw channel 2 , the rib 5 c can be designed with barb-like shapes. These barb-like extensions are not expressly identified in FIGS. 7 and 8. The rib 5 c is not expressly designated by the web 13 e in FIGS . 7 and 8. The rib 5 c projects from the web 13 e in FIGS. 7 and 8 downwards in the direction of the lips 5 a, 5 b and parallel to the sections 13 e, 13 d.

From the above description it can be seen that, depending on the seals shown in FIGS. 7 and 8, the condensate drainage or drainage is achieved on two different levels and overlapping in the seal joint, so that the condensate at the crossing points from the higher level (transom seal according to Fig 7) (in the lower level post gasket. FIG. 8) flows.

Fig. 9 finally shows a device for fastening glazing, facades or the like with a Anschlusspro fil 1 , on the upper wall 1 a an integrally formed screw channel 2 is provided, as it corresponds to the embodiment of FIG. 3, while on a side wall 1 b a U-section made of steel is welded on, which serves as a screw channel and is designated 32 . The arrangement shown in Fig. 9 serves as a fastening profile for corner designs of facades or the like using the described seal 5 in the area of both screw channels 2 , 2 ', wherein in the corner area between the glazing elements 6 a, 6 b tubular profiles 34 , 35 are used for mounting a corner covering 36 .
