A QCD coupling in which a rotating subsidiary locking means is provided which is both positive in its locking action, locks all of the levers simultaneously, and does not involve any small or readily losable parts, as the subsidiary locking means is itself securely attached to the coupler part of the QCD coupling. As all of the levers are locked simultaneously, the subsidiary locking means cannot be locked unless all of the levers are in the fully "locked" position.

1. A female coupler for a quick connect/disconnect coupling comprising in combination:a female coupler comprising a body member having a bore for receiving the outer end portion of the male adapter, and a seal constructed and arranged to seal with the sealing surface of the male adapter; a lever locking mechanism carried by the female coupler comprising a plurality of locking levers pivotally mounted onto the outside of the female coupler, each lever being rotatable between a "closed" position, and an "open position; a cam member attached to or forming part of each lever extendable on rotation of each lever about its pivot toward its "closed" position through a corresponding slot in the female coupler body into the bore of the female coupler, the cam members being constructed and arranged to engage with a cooperating arcuate groove on a male adapter constructed and arranged to be connected to a second fluid conduit entered into the bore of the female coupler on rotation of the levers toward their "closed" position; a cap member rotatably attached to the female coupler adjacent the opening of the bore, the cap member having a skirt which extends along the outside of the female coupling to a point adjacent the lever pivots, and being rotatable on the female coupling between a "closed" position, and an "open" position; a plurality of slots in the skirt of the cap in registration with the levers; and at least one detent means interposed between the cap and the female coupler constructed and arranged to retain the cap in its "closed" position; wherein when the cap is in its "open" position the levers can be moved into the cap slots to their "open" positions, and when all the levers are rotated to their "closed" positions, the cap can be rotated about the female coupling to its "closed" position.
