Abstract: A connector assembly comprises a male and a female connector, the male connector having releasable lock means on its shank. The lock means includes a plurality of radially extending tongues extending outwardly from such shank, the tongues being compressible to fit within the bore of the female connector during assembly and disassembly of the connectors. The female connector includes a recess or chamber in the bore for receiving the tongues to lock the connectors together, and a flange against which the tongues may react to enable compression of the tongues an disassembly of the connectors.
