ABSTRACT:
A flow-through or fluid coupling connector assembly possessing positive locking connect and ready disconnect comprising two connector bodies; one having a male tubular member, and the other having a female tubular member for receiving the male member upon connection of the two bodies together. The male tubular member of the one connector body has resilient arm members spaced from and extending along opposite sides of the tubular member's axis with the free remote ends of the arms flaring outwardly therefrom. The arm members are each provided with an inwardly projecting flange member for locking the two connector bodies together by fitting into a recessed collar on the other connector body. The other connector body has projections at opposite sides thereof which are of a size and spaced to bear outwardly against the arm members of the one connector body, the spacing being such that on rotation of one of the connector bodies relative to the other, the projections bear against the arms to spread them and lift the flanges out of the recessed collar for separation of the bodies.
