A coupling seat provides a seat space in which the coupling head of a coupling bolt can be releasably locked and moved linearly in the seat space. The seat has a wall that surrounds the seat space, and the dome has a locking structure to fasten the coupling seat in an installation opening in a component. The seat has an open end and a closed end with a locking structure for the head of the coupling bolt. The locking structure of the dome comprises latching bars that are arranged opposite each other on an inner wall of the seat space and parallel to a longitudinal axis of an inner dome cross-section and form an undercut opposite the insertion direction. The locking structure permits movement of a coupling bolt along the latching bars in the seat space transverse to the insertion direction.

Plug-in coupling with tolerance compensation

A tolerance compensation element that compensates for tolerances in the distance between first and second components, includes a thread bolt having a first drive feature, a first thread of a first thread direction and a second thread of a second thread direction. Between the first and the second thread, a protrusion extends from the thread bolt radially to the outside. The element includes a first plastic overmold in the portion of the first thread, which provides a fastening structure for the fastening to the first component, and a second plastic overmold around the protrusion which extends radially to the outside, to provide an abutment portion abutting the second component when in use. A distance of the second plastic overmold to the first plastic overmold is changeable after overcoming a start-up torque between the first plastic overmold and the first thread in longitudinal direction of the thread bolt.
