Abstract: A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.
