ABSTRACT:
A snap-closure coupling for flowing medium ducts has two halves one of which can be plugged into the other. The arrangement is such that the flow paths through both the plug half (which is connected to a medium source) and through the socket or sleeve half (which is connected to a reservoir, such as the applied brakes of a trailer) will be blocked when the plug half is pressureless and the sleeve half is pressurized. However, when the plug half is inserted into the sleeve half, the flow paths through both halves are automatically opened.
