ABSTRACT:
The pipe connector comprises a pin member and a box member which have outer and inner generally frusto-conical peripheral surfaces which overlie one another when the members are fully engaged together. To axially lock the members together, the surfaces are provided with interengaging annular projections and grooves. For disengagement of the members, pressurized fluid is supplied between the peripheral surfaces through an inlet in the box member. The ends of the peripheral surfaces are sealed, during disengagement, by providing reversely inclined annular surfaces on the free ends of the pin and box members and correspondingly at the roots of the box and pin members. In use of the connector these inclined surfaces are slightly spaced apart and are brought into sealing contact on application of pressurized fluid between the peripheral surfaces.
