Abstract: A pipe connector for connection to a pipe having a plain end comprises a body having a profile matching that of the pipe, and a pair of jaws extending outwardly for insertion within the end of the pipe. The jaws are formed with oppositely directed clamping surfaces for engaging the inner wall surface of the pipe end. One of the jaws is fixed and integral with the body. The other jaw is pivotally mounted on the fixed jaw and is extended inwardly of the body where it is threadedly engaged by a screw which connects the pivoted jaw with the body so that by rotating the screw in the appropriate direction the pivoted jaw pivots away from or towards the fixed jaw to clamp or unclamp the jaws from the pipe. The screw thus provides a positive clamping force which greatly assists the dismantling of the connector from a pipe end when desired. The screw also retains the pivoted jaw in place and there are no loose parts to become lost.
