ABSTRACT:
A coupling assembly for joining two fluid conduits together, consisting of a female component and a male component. Female component integrally construction of resilient material has a portion for snugly mating with a male component on one end, another portion for attaching a conduit on the opposing end, and internal valve means. Male component, that snugly press fits into the female component, has a mating portion with internal valve means and a conduit attachment portion. Valve means of assembly permits fluid flow when both components are fully engaged and terminates fluid flow when they are disengaged. Both components can be effortlessly couple together with a relatively low compressive force and automatically separate with a relatively low tensile force.
