Abstract
A connection device for connection to first and second fluid conduits for providing selective fluid communication between the two conduits. The connection device comprises a first member having first and second open ends and a fluid passageway therebetween, and a second member having a first open end and a second end with a fluid passage defined therebetween and in which the second end is disposed within the second open end of the first member. The first and second members are movable relative to one another between an open position in which the first fluid passageway in the first member and the second fluid passageway in the second member are in fluid communication with one another, and a closed position. Closure means are provided associated with the second ends of at least one of the first and second members for closing one of the first and second passageways to prevent the fluid communication therethrough between the first ends of the first and second members when the second member is in a closed position. Bias means are provided for biasing the second member towards the closed position when the second member is moved towards the open position.
