A quick connect coupling for fluid conduits having an outer cylindrical member and an inner conduit fitted within the outer cylindrical member including a continuous circular gripper ring seated in the outer cylindrical member and having radially inward gripper teeth bent axially forward toward the outer cylindrical member in a generally conical plane, each tooth has a twist in a common direction whereby the inner conduit can be slid into the gripper ring but removed from the gripper ring only by unscrewing from the gripper ring.

Fluid conduit coupling apparatus, comprising: a conduit housing having a circular bore, an axially inner shoulder, and a flange extending radially inward from said circular bore; a bushing seated in said circular bore; a sealing member seated in said circular bore; a seal retainer for holding said seal within said circular bore; and a circular gripper rings, said gripper ring having a plurality of inner circumferentially spaced teeth forming an inner circle of said ring and the inner circle adapted to be of a diameter less than a tubular fluid conduit to be inserted therein whereby a frictional engagement occurs between the conduit and said teeth, with the teeth being elastically deformed axially forwardly as the conduit is inserted, said gripper ring having a notch corresponding to the flange of said circular bore to prevent rotation of said gripper ring relative to said circular bore, said teeth having radially inner edges which dig into the conduit if the conduit is retracted straight out to hold the conduit within the housing, said teeth each lying generally in a radially inwardly converging conical plane, each tooth having a twist in a common direction at an angle to said conical plane whereby rotation of said conduit while being retracted will cause the conduit to thread out of said angled teeth.
