To make possible a simplified coupling maneuver and to ensure an increased level of safety, the catch unit (15) comprises at least one catch hook (16) which is swivel-mounted on the carrier assembly (2) [sic] and on which a control member (24) for controlling the swivel movement of the catch hook (16) between a folded-in and a foldedout position is disposed, said control element being designed to be actuated by the first coupling 5 member (5) and being actuated independently of the locking unit (11).
