ABSTRACT:
A connector assembly is disclosed for rapidly forming a secure fluid-tight connection in a fluid circuit. The proximal ends of the fittings are adapted for connection with tubing, hose or other fittings of the circuit. An annular connector cap is formed at its opposite ends with inwardly projecting detent shoulders. One detent shoulder is sized for engagement in an annular locking groove formed about the outer surface of the female fitting while the other detent shoulder is sized for locking engagement with one of a series of annular locking barbs formed about the male fitting. Inclined camming surfaces are associated with the barbs for camming the corresponding detent shoulder radially outwardly and thereby facilitate locking of the detent with a selected barb which securely holds the fittings together in fluid-tight relationship. The cap is formed of a resilient material while at the same time circumferentially spaced slots are provided about the ends of the cap to permit flexing of the detent shoulders upon engagement with the respective locking groove and barbs.
