Abstract
The device for fastening an object to a wall or the like by a push-in mounting, comprises an externally threaded bolt, at one end of which a nut can be threadedly advanced, and on the other end which is at least partially conical and whose maximum diameter is at most equal to the diameter of the bolt, has displaceably mounted thereon an expander element composed of two half-shell like parts. The two parts of the expander element are provided at their longitudinal edges opposite to one another in the mounted condition with integral lobes disposed transversely symmetrical and, when viewed in development, point-symmetrical, in relation to one another. The edges of the lobes are formed in such a way as to provide, when disposed on the externally threaded bolt, a form-locking connection.
