Abstract
A quick-disconnect coupling such as a camlock includes a hollow male plug with an external peripheral groove and a hollow female socket defining a duct for communication of a fluid with a locking arrangement for locking the male plug in the female socket. Protrusions are provided on either an inside surface of the female socket or on an outside surface of the male plug and corresponding recesses are provided on the other with the recesses and protrusions being cooperatively shaped and arranged to allow insertion of the male plug member into the female socket member to the locking position only when at least one recess and at least one protrusion match.
