A further object of our inassist grips or hand holds having the Vgeneral vention has been to provide means, associated purposes and uses of the Well known automobile With the end device fastening means, whereby ttings such as robe rails which are suspended the mold may be held in normal operative posibetween supports at both ends and/or grip straps tion without the use of glue, thus doing away with I5` in which a pompon, gripping member, or the like, an undesirable ingredient in .the finished product. is fastened to one end of a suitable stem, freand eliminating the gluing operation to the adquently in the form of a piece of rope or cord, Vantage of the manufacturer.` the other end of said stem carrying a bracket Preferred embodiments of our invention are l0A or other suitable means for attaching the hand illustrated'in the drawing appended to the presen 10 hold to the interior of an automobile.

The clamping portions 1 are number of parts and adapted to be assembled provided with recesses or perforations 9, prongs with the stem in a simple and expeditious manner. l0 displaced or upset outwardly from the normal 50 In grip strap construction it has also been cussurface of the blank, and inwardly directed protomary to employ a ferrule, sometimes called a jections I9 for purposes hereinafter to be more mold, for the purpose of concealing the joint or ully explained. fastening between the pompon or end device and When in operative position on the stem I,

` the stem. This mold is commonly glued in its Strap 6 encircles a portion of the pompon 2 while 55 the end or clamping portions I of the blank engage the stem I near its lower end, the terminal edges II and/or the projections I9 of the blank being pressed inwardly into or against the stem to compress and securely engage the same. When the lateral edges of the respective clamping ends 'l are brought adjacent to each other by suitable assembling implements, a tongue' of one clamp overlies a portion of the other clamp in position to be deflected to engage the recess or perforation 9 thereof. In making theform of device shown, the free end of the tongue 8 is pressed inwardly through or into said recess or opening 9 in the other clamp, thus interlocking the clamping ends, and where the tongue is long enough, presenting an inwardly directed projection as I2, Figure 3 extending into and further compressing the stem.

The prongs IIJ projecting outwardly from the clamping members are arranged to permit the mold 4 to be moved longitudinally in one direction into clamp covering or concealing position, but to oppose the removal or displacement of the mold in the opposite direction. As shown, the points of prongs I extend downwardly and project sufciently beyond the outer'surfacesl of the clamping members to engage portions of the interior surface of the mold. When the latter is moved into operative position, the endsr of the prongs I0 may yield sufciently for the purpose; but, where the mold core is made of wood, or is of other suitable construction, the sharpened points will extend into or otherwise engage it, to oppose the withdrawal or removal of the mold.

The illustrated bracket fastening means, usually concealed by a suitable covering 5, comprises a single metallic member bent to form a bracket holding loop I3 between stem gripping or clamping portions I4 provided with inwardly projecting prongs I5. In assembling the bracket fastening device with the stem, as I of the-toggle grip shown in Figure 1, or I6 of the robe rail shown in Figure 6,7the clamps I4 are brought into stem compressing position and, Ywhile in Ysaid position, a band or ferrule II is slid into clamp embracing position and is there crimped at I8, or otherwise treated or manipulated to secure the clamps I4 in operative stem engaging and compressing position and with the prongs I extending inwardly and into the stem I.

From the foregoing description and statement of method of making our improved grip or hand hold, it will be apparent that we have provided a pompon fastening construction employing opposed stem clamping elements which are held in positive and practically unyielding engagement with the stem, as distinguished from other forms in which the security of the fastening is in great measure dependent on the stiffness of the Wire or other material used in the clamp. Our fastening device is of simple construction andeasily and effectively aixed to the end of a stem. Furthermore, when equipped with projections such as the prongs I0, the described clamping device also serves to retain the mold in operative clamp concealing position without the use of glue or other separate instrumentality for the purpose. The described bracket fastening means also utilizes opposed clamping elements which are held in operative position by any suitable device such as the band II or other equivalent thereof, thus maintaining the prongs I5 in effective engagement with the stem I to prevent endwise displacement of the clamps I4 when the stem is subjected to strain or tension.

We claim:-

1. An assist grip comprising a stem, a pompon and a pompon fastening member co-operating with the stem and having interlocking clamp portions at its ends compressibly engaging the stem and a strap portion integral with and connecting said clamps and embracing a portion of the pomp-on.

2. An assist grip comprising a stem, an end device thereon and a fastener having a loop portion to retain saidend device and opposed clamp portions compressibly engaging a portion of the stem between-them and a separate annular metalcollar embracing portions of said clamps and having a deformation extending inwardly be` tween the edges of the clamps.
