Abstract: A fastening device for detachably fitting protective covers on upholstered foam material, such as seat cushions, seat backs or mattresses, by means of upholstery buttons which can be attached to the fastening device in the manner of snap fasteners. The fastening device consists of a connecting tape (1) on both ends of which are molded attached end pieces (2, 3) which have spherical heads (4) and (5) onto which the upholstery buttons can be pressed. One attached end piece (2) has on the side facing the tape a cylindrical stem (12) and on the stem, at a short distance from the head, is a stop plate (6) for holding the attached end piece (2) against one side of the foam. The other attached end piece has on its side facing the tape, a stem (12) on which is located, at a short distance from its head (5), a smaller support plate (7) whose diameter corresponds approximately to the diameter of the spherical head (5).

Abstract: An anchoring plug made from a hard-elastic plastic material having a closed shank part 1 and two mutually opposite spreading fingers 2 and 3. A screw hole 10, extends through the shank part 1 down into a central space 12 between the spreading fingers for receipt of a screw 18. To be able to drive the plug directly into gypsum board without having to first drill a hole, one spreading finger 2 is longer than the other spreading finger and has a hook-shaped tip 4 forming a recess 5 at its free end. Initially the end of the shorter spreading finger 3 nests in this recess to provide a pointed end to the plug, but springs free of the recess when a screw is screwed into the plug.

Abstract: A holder for holding a cable or hose passing through an opening in a wall in sealed manner including a cylindrical receiving body part made of a flexible elastic material and an annular holding body part made of an inflexible plastic material. The receiving body part has a front end and a rear end with an axially extending opening therein for receiving the cable or hose and a locking edge extending circumferentially around its outer peripheral surface. The annular holding body part has a front end and a rear end with an opening extending between its ends sized to axially receive the receiving body part. Locking tabs are provided on the front end of the holding body part for anchoring it in the opening in the wall and inwardly extending radial locking noses are provided on the rear end of the holding body part for engagement with locking edge on the receiving body part, whereby when the front end of the receiving body part is inserted into the rear end of the holding body part the two parts are axially locked.

Abstract: A releasable plug connection for semi-rigid pipes in which the elastic retaining ring for holding a pipe in the connection is seated in a flanged ring portion of the stop ring that limits opening movement of the spring taps of the retaining ring and a supporting ring is located between an end face of the flanged ring portion and a plurality of shoulders spaced around the periphery of the entrance to the connection to hold the retaining ring in place.

Abstract: A mounting unit for attaching supply lines or cables to a motor vehicle by means of socket bolts, and in particular to threaded bolts located on the underside of the vehicle's chassis, and cable holders for use in forming the mounting units, the cable holders have a fixing part of securing the holders to the bolts, arms for holding the cables in the holder and elastically latchable an dunlatchable connecting hooks and apertures for connecting the holders together. This permits the units to be stacked one on top of the other by connecting their holders together to keep the holders accurately positioned along the length of lines or cables during transport and prior to assembly of the units to the vehicle.

Abstract: A guard ring for long distance transmission cables for preventing wet snow from accumulating on the cables. The guard ring consists of two half collars of a hard elastic plastic material integrally joined by a hinge strap at one end and having interlocking hooks at their free ends to form a closed ring that tightly encloses the cable. Beaks or the like are integral with the inner ends of the half collars and face each other in the area of the hinge. The beaks cover a part of the hinge strap from both sides, so that when the half collars are open, they form, together with the hinge strap, a T-shaped groove for conveniently holding the rings in a row, prior to assembly, on a corresponding T-shaped rail. When the half-collars are closed and the ring secured to the cable, the beaks are bent apart a sufficient distance so that the rings can easily be removed from the rail. An assembly tool is also provided for clamping the rings about the cable.
