Abstract: For an electrical plug and socket connection with housing halves that can be locked together, for which a sleeve, which can be shifted in the longitudinal direction of the housing halves, is provided for cancelling the locking, it is proposed that the locking elements be constructed as latches, which grip behind the locking shoulder at the one half of the housing in order to lock the two halves of the housing together. For this purpose, the latches are provided with an inclined surface, which is acted upon by an edge of the sleeve to unlock the connection. When tension is applied to the sleeve in a direction opposite to the plug-in direction, the edge of the sleeve presses the latches out of the locking position.
