ABSTRACT:
A quick connect-disconnect coupling for a fluid conduit structure and method of making same are provided wherein the conduit structure has cam devices for connecting and disconnecting a coupler member and an adapter member comprising the coupling and the cam devices cooperate during disconnection of the members to provide a disconnecting movement from a first axial position thereof until a second position is reached at which second axial position the disconnecting movement is reversed and becomes an incremental connecting movement for a predetermined increment to a third axial position of the members before allowing the members to be completely disconnected, the coupling having seal means that provides a fluid-tight seal between the members during the entire time the members are being moved from the first axial position thereof to the third axial position thereof.
