Coupling has locking protrusion which in extended position of plug-in component when it is not properly fitted in housing component prevents movement of locking component into inserted position

摘要

The coupling has a housing component (1) to accommodate a plug-in component (17), and a locking component (9) with at least one locking arm (13) and at least one retaining arm (11). The locking arm is flexible in the axial direction, and the dimension of the locking arm socket (4) in the axial direction is larger than the thickness of the locking arm. A locking protrusion (6) in the extended position of the plug-in component when it is not properly fitted in the housing component prevents the movement of the locking component into the inserted position.
