ABSTRACT:
A connector for and a method of connecting pipe members for a variety of purposes including (but not limited to) plumbing, hydraulics, pneumatics and medical purposes. Wherein the connector which can be used in conjunction with other fittings, has a connector body with an opening to receive a pipe and a tapered internal bore in the opening to receive a substantially coaxial inner sleeve adapted to engage the surface of the pipe in the connector. After insertion, the pipe is then moved in an opposite direction to the direction of insertion and the inner sleeve is adapted to slide wherein internal bore to wedge into frictional engagement and connection with the outer surface of the pipe and the tapered surface of the internal bore so that when the pipe is sealably engaged within the connector the pipe can be disengaged from the connector by a reverse operation. The connector has the advantage that a pipe may be sealably engaged in the connector without the necessity to work the pipe, in a connector comprised of two components manufactured of plastic materials. The inner sleeve may have sealing ridges to increase the sealing capabilities of the connector.
