System made up of an attachment part and a retaining element

A system comprising:

• an attachment part (44) and a holding element, the holding element holding the attachment part (44) on a carrier part (54), the holding element comprising a threaded part (10) releasably connected to the attachment part (44) and having an internal thread (28) receiving a holding screw (58), and a spacer part (30), the spacer part (30) and the threaded part (10) having interacting threads (26, 38) such that the spacer part (30) is screwed to the threaded part (10), and the spacer part (30) having a through opening (56) receiving the holding screw (58), which through opening (56) is flush with the internal thread (28) of the threaded part (10) when the spacer part is fully screwed onto the threaded part (10), wherein the carrier part (54) is held between a head (62) of the holding screw (58) and the spacer part (30), wherein the threaded part (10) has a holding section (11) for holding the attachment part (44), the holding section (11) having at least one latching element which interacts with at least one corresponding latching element of the attachment part (44) for releasably latching the attachment part (44) on the threaded part (10), wherein the through opening of the spacer part (30) has a plurality of clamping sections (42) such that the holding screw (58) drives the spacer part (30) in a clamping manner, wherein the each clamping section (42) is formed by a respective radially inwardly extending and axially running portion of a wall of the through opening of the spacer part (30), wherein the holding section (11) is engaged in an opening of the attachment part, wherein the opening in the attachment part is a receiving groove formed by a C-shaped wall section.

A system comprising:

• an attachment part (44) and a holding element, the holding element holding the attachment part (44) on a carrier part (54), the holding element comprising a threaded part (10) releasably connected to the attachment part (44) and having an internal thread (28) receiving a holding screw (58), and a spacer part (30), the spacer part (30) and the threaded part (10) having interacting threads (26, 38) such that the spacer part (30) is screwed to the threaded part (10), and the spacer part (30) having a through opening (56) receiving the holding screw (58), which through opening (56) is flush with the internal thread (28) of the threaded part (10) when the spacer part is fully screwed onto the threaded part (10), wherein the carrier part (54) is held between a head (62) of the holding screw (58) and the spacer part (30), wherein the threaded part (10) has a holding section (11) for holding the attachment part (44), the holding section (11) having at least one latching element which interacts with at least one corresponding latching element of the attachment part (44) for releasably latching the attachment part (44) on the threaded part (10), wherein the internal thread (28) of the threaded part (10) and the interacting threads (26, 38) of the threaded part (10) and the spacer part (30) are configured in such a way that rotation of the holding screw (58) for screwing into the internal thread (28) of the threaded part (10) causes the spacer part (30) to unscrew from the threaded part (10), wherein a stop is provided between the spacer part (30) and the threaded part (10), which stop counteracts the spacer part (30) from being unscrewed from the threaded part (10) when an end position is reached, wherein the threaded part (10) includes a plate (18), wherein the stop comprises a rigid stop arm (24) extending from the plate (18) and a stop face located on the spacer part (30) for contacting the rigid stop arm at the end position.
