A coupling half designed to mate with an identical coupling half to form a coupling for interconnecting sections of hose or the like, has a tubular body having at one end a projecting tooth and a complementary socket arrangement constituted by a plurality of uniformly spaced arcuate connector teeth axially outstanding from the tubular body and terminating in a radially inwardly directed arcuate protrusion, a plurality of radially outwardly directed arcuate ribs circumferentially aligned with the teeth, and a plurality of tooth entrance ways located circumferentially between each of the ribs and each of the teeth, a resiliently biased detent locking device in the body biased towards an advanced position, and an annular detent unlocking ring angularly rotatable on the body and resiliently biased in one direction of rotation to an inoperative position and being angularly movable in the opposite direction to an active position wherein it engages the detent locking means to retract it away from the advanced position. |
