A quick connect fitting in which tubing can be inserted into a pre-assembled fitting where it will become sealed and locked against pull-out. A main fitting body has an open-ended recess in which is located a movable piston to seal against the body and an inserted tube. The piston wedges over a conical extension on a sealing gland retained by a screw-on cap. The sealing gland has rearward, circumferentially spaced fingers radially movable. An axially shiftable ring, in one position, allows the fingers to expand to receive the tube, and, when shifted to a second position, moves the finger to engage the extension surface of the tube to lock against withdrawal.
