Abstract: A securing device for a pre-assembly of a pin-shaped connecting element in a through-opening of a component The securing element includes a sleeve with and an inner side and with a flat outer wall having a recess arranged therein, and holding elements each of which protrude inwardly. The holding elements are arranged on the inner side of the sleeve. The recess is arranged into the flat outer wall of the sleeve and provides a latching engagement of a lug which is arranged in the through-opening during the pre-assembly.

Abstract: A fastening system with

Abstract: A fastening system comprises a screw including a thread formed on a shank and configured to form a threaded bore in a plug made of a plastic material, and at least one notch formed in the shank between at least two adjacent turns of the thread. The system also comprises a clip including first and second clip bows connected at joined portions thereof. The first and second clip bows further have firs and second through apertures in their central portions which are aligned and sized to define a channel for allowing the shank of the screw to pass through. At least one of the first and second through apertures has an internal thread matching with the thread of the screw. The clip has at least one resilient lug adapted to engage with the at least one notch when the screw is fastened into the internal thread.

Abstract: An arrangement for fastening of an assembly part on a carrier part includes at least one fastening screw, a sleeve, and a flexible assembly ring whose inner diameter is smaller than an outer diameter of a sleeve head flange and foot flange and which is arranged between the head flange and foot flange on the sleeve. The assembly part includes a through-bore in the assembly part whose inner diameter is at lest as large as the outer diameter of the foot flange, into which the sleeve is inserted. The lower side of the head flange is indirectly or directly supported on the upper edge region of the through-bore. 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.
