A coupling for connecting fluid conduits comprises a coupler and an adapter. The coupler has a frusto-conical seat at its distal end. Fixed and pivotal jaws project beyond the frusto-conical seat and are engageable with a clamping surface on the adapter. A lever operated, cam member swings the pivotal jaw to a position in which the coupler is locked in sealed relation on the adapter. An interlock rod prevents rotation of the lever from this rest position unless the coupler is positioned to be locked on the adapter. The coupler and adapter each comprise normally closed poppet valves. When the operating lever is swung from its rest position to a ready position, the pivotal jaw is swung to its locking position. When the operating letter is swung to a further angular extent, to a full flow position, the coupler poppet is displaced outwardly by a crank/link mechanism. When the coupler poppet is so displaced, it engages the adapter poppet and positions both poppets in open positions, interiorly of an adapter housing passageway. Manual release means require selective actuation for the operating lever to be swung from the rest position to the ready position and to permit the lever to be swung from the ready position to either the rest position or the full flow position.

A coupling for joining fluid conduits, comprising: an adapter having a first end connectable to a first fluid conduit, a second end, an adapter housing extending between the first and second ends and defining a central passageway, and a clamping surface spaced axially inwardly of the second end; a coupler having a first end connectable to a second fluid conduit, a second end, a coupler housing extending between the first and second ends and defining a central passageway, a pivoted jaw projecting longitudinally beyond the second end, said pivoted jaw being selectively engageable with the clamping surface of the adapter, and a fixed jaw projecting longitudinally beyond the second end, said fixed jaw being engageable with the clamping surface of the adapter; and a locking mechanism for selectively securing the pivoted jaw against the clamping surface of the adapter. A coupling as recited in claim 6 wherein the coupling further comprises a first normally closed valve seated within the central passageway of the adapter, a second normally closed valve seated within the central passageway of the coupler, and a displacement mechanism for displacing the coupler and adapter valves between an open and closed position when the pivoted jaw is secured by the locking mechanism.
