Abstract
A quick connect coupling is disclosed providing a body assembly having a tube end receiving passage proportioned to closely fit the forward end of a tube. A seal is located in the body assembly to provide a fluid tight joint between the end of the tube and the body assembly. The body assembly also includes a lock ring retaining groove within a nut with an expandable lock ring positioned therein. Mounted on the tube at a location spaced from the end thereof is a locking sleeve which is crimped inwardly toward a tubular insert to lock the locking sleeve in position. The forward end of the locking sleeve is formed with a camming ramp which extends toward a lock ring groove. Assembly of the coupling requires the mere axial movement of the tube end assembly into the body assembly until the seal engages the outer surface of the tube and the lock ring bridges between the nut groove and the lock sleeve groove to permanently connect the tube end and the nut.
