Abstract

A fastening of an assembly part on a carrier part with - at least one fastening screw which comprises a screw head with engaging surfaces for a tool, a screw shank, at least one radial projection on the screw shank at a distance from the screw head and a thread at least at the distance of the radial projection from the screw head, - with a sleeve with an inner diameter which corresponds at least to the outer diameter of the radial projection and of the thread, which is a narrow location with an inner diameter smaller than the diameter of the radial projection but at least as large as the outer diameter of the screw shank between the screw head and the radial projection, and which at the upper end comprises a head flange and at the lower end a foot flange into which the fastening screw is inserted, wherein the narrow location is snapped over the radial projection of the fastening screw and the screw head is allocated to the outer side of the head flange, - with a flexible assembly ring whose inner diameter is smaller than the outer diameter of the head flange and foot flange and which is arranged between the head flange and foot flange on the sleeve, - with a through-bore in the assembly part whose inner diameter is at least as large as the outer diameter of the foot flange, into which the sleeve is inserted, wherein the lower side of the head flange is indirectly or directly supported on the upper edge region of the through-bore, wherein however the inner diameter of the through-bore is dimensioned such that the assembly ring is radially pressed together therein and by way of this clamped in and/or the through-bore comprises an undercut with an inner diameter so that the assembly ring under radial compression and subsequent expansion is pushed through the undercut and by which the assembly ring is retained in the through-bore, and - with a threaded bore in the carrier part, into which is screwed the thread of the fastening screw and on whose edge region the foot flange of the sleeve is supported.
