A coaxial quick disconnect coupling for coaxial fluid lines including an external plug-and-socket combination having an internal plug and socket mounted coaxially therein. Preferably, the internal plug member is mounted within the external socket portion of the connector while the internal socket is mounted within the external plug portion. Valves incorporated in the internal plug and socket prevent flow of the fluid in the coaxial line when the assembly is disconnected.

A coupling member for making inline connections of the respective ends of both the inside and outside conduits in “coaxial”type telescoped fluid lines, comprising: a mutually engageable first plug member and said socket member each having an end portion with means for attaching thereto the respective ends of one of said fluid conduit lines at an interruption therein and having a passageway therethrough for passage of a first fluid; attachment means on said plug and said first socket for releasably connecting same together when mutually engaged; a second plug member and a second socket member positioned in telescoping relation with respect to said first plug and said first socket member; said second plug and said second socket each having an end portion with means for attaching thereto the respective ends of a different one of said fluid conduit lines at an interruption therein and having a passageway therethrough for passage of a second fluid, said second plug and socket having portions which cooperatively engage each other when said first plug and socket are connected; means mounting portions, including at least the said end portions, of at least one of said first or second plug or socket members so as to be angularly movable about the longitudinal axis of the corresponding part of the coupling which is in telescoping relation with such plug or socket members; and valve means in at least one of said first and said second plug and said first and said second socket to control flow of fluid in at least one of said first and said second passageways.
