ABSTRACT:
A tube coupling for co-axial tubing includes a body having a throughway open at one end to receive an end portion of a length of co-axial tubing. The throughway has an annular seat spaced from the open end to receive the outer tube of the co-axial tubing and a tube locking means disposed between the seat and the open end to receive and lock the tubing in the throughway. A conduit is mounted concentrically in the throughway and is connected integrally with the coupling body to receive an inner tube of the co-axial tubing to provide a separate passageway extending concentrically within the throughway.
