A valve device having a tubular body adapted to be connected in a fluid conduit system. A self-closing valve member is pivotally mounted in the passage of the tubular body, the pivotal valve member being in a position closing the passage when the device is in a disconnected state and in an open, interlocked position when the device is in a connected state. The valve member is adapted to be pivoted from a closed position to an open position and when in the open position, moved axially with respect to the passage of the tubular body to a position whereat it is supported on a retaining lip provided in the tubular body.

In a valve connector of the type having a pair of interconnectable body members, each having a central passage extending therethrough, a valve member pivotally mounted in the passage of one of the body members wherein the valve member is in a position closing the passage when the body members are uncoupled and in a position opening the passage when the body members are coupled and connecting means for interconnecting the body members, the improvement comprising: (a) a piston axially slidably mounted within said one body member and having a central aperture with the passage in said one body member; (b) said valve member being pivotally mounted on said piston over the central aperture therein and pivotal between positions closing and opening the central aperture; (c) means for urging said piston to a first position whereat said valve member closes the aperture in said piston when said body members are in the uncoupled state; (d) means for pivoting said valve member from its closed position to its open position when said body members are in the coupled state; and (e) means for axially moving said piston and said open valve member to a second position interlocking said valve member to said one body member when said body members are in the coupled state.
