A connector includes first and second plug-and-socket connector parts and a connection element. The first connector part has a latch operable to connect the connector parts together. The connection element is connected and is displaceable with respect to the first connector part between first and second positions. The connection element has a pair of locking tabs operable with the latch such that the connection element is fixed in the first position until the latch connects the connector parts together and such that the connection element is movable from the first position to the second position when the latch connects the connector parts together. While in the first position the locking tabs release the latch connection such that the connector parts are separable from one another. While in the second position the locking tabs secure the latch connection such that the connector parts are securable connected to one another.
