Abstract
A quick pipe connector includes a tubular housing defining an axis, and a connecting unit. The connecting unit includes a grip ring adapted to grip a water pipe, and a locking ring abutting against a first housing shoulder surface of the tubular housing and positioning the grip ring to abut against a second housing shoulder surface of the tubular housing. The locking ring has a slit that extends parallel to the axis. An inner ring surface of the locking ring includes an annular inner shoulder part transverse to the axis. A release ring is formed with a stop surface confronting the annular inner shoulder part, and is movable along the axis relative to the locking ring to a release position, where the stop surface is moved away from the annular inner shoulder part and where the release ring forces the grip ring to release gripping action on the water pipe.
