The tongue can be engaged with an engagement edge by at least one latch which is movable transversely to the plug-in direction of the plug-in tongue. The latch in the region of the engagement edge of the plug-in tongue has a profile which comes close to complementing the shape of the engagement edge as it changes under load.
