ABSTRACT:
An improved quick connect and disconnect pipe joint fitting has a cylindrical body with a truncated cone-shaped internal wall. A sleeve having a plurality of spaced-apart tabs on the end thereof is received in the sleeve. The tabs each have a straight inner surface and a cone-shaped outer surface, the outer surface cooperating with the cone-shaped inner wall of the hollow cylinder. When a pipe is inserted in the sleeve received in the hollow cylinder, the tabs are moved outwardly. When the sleeve is moved outwardly from the hollow cylinder the smooth inner surfaces of the tabs are wedged against the pipe, thereby locking the pipe in the pipe joint fitting.
