ABSTRACT:
A quick-disconnect cam locking safety coupling has a hollow male plug having an external peripheral groove. The plug is received in a socket. The socket has a pair of opposed openings opposite the peripheral groove. A gasket seals between the male plug and the socket. A pair of cam members each has a lever lying adjacent the socket and a cam portion passing through one of said side openings and engaging the peripheral groove. Each cam member is pivotally connected to the socket for outward movement of the levers away from the socket to disengage the cam portions from the peripheral groove. Each cam member is locked in the groove engaging position by a removable wire pin engaged by at least one lug on the socket and adapted to limit the outward movement of the cam member lever.
