ABSTRACT:
A connector for connecting a first pipe end and a second pipe end, one of which leads from a pressurized source, wherein a normally closed valve member is provided in the pipe from the pressurized source and an axially movable valve stem extends from the pressurized pipe and wherein the valve mechanism includes a spring normally urging the valve stem into a first position in which the valve is closed and the second pipe includes an axially movable member for axially moving the valve stem to open the valve when the pipes are interconnected together and wherein seals are provided and are effective to define a closed flow path through the pipes when the pipes are connected together.
