• and at least one user gripping means (70) on an exterior surface of the rotatable connector (50) to assist a user in the coupling/screwing of the rotatable connector (50) to the cylindrical male outlet (22) of the source of medical gas (20), the gripping means (70) is chosen from physical gripping means including, but not limited to, grooves, fingertip indentations, radially protruding flanges, angled surfaces and edges, curved surfaces and edges, surface bumps and friction-causing rough surfaces;
• and at least one physical barrier (86) that prevents the rotatable connector (50) from sliding up and down back and forth any distance along the flexible cylindrical elastomeric medical gas tubing (30), said at least one physical barrier (86) provided for preventing the rotatable connector (50) from sliding is chosen from such distance limiting structures including, but not limited to, at least one an annular flange, washer, O-ring, dimple, bump, clasp and wedge, on or as part of the flexible cylindrical elastomeric medical gas tubing (30) and/or tubing bushing (40), said barrier (86) unable to pass through the second opening (56) of the second end (58) of the rotatable connector (50) in a resting state.
