ABSTRACT:
The invention comprises a metal push-in tube fitting and a release tool. The metal tube fitting includes a body with a tube-receiving cavity in one end. A tube support forms the inside of the cavity and supports the tube against inward movement. A gripper ring having a radially inner gripping edge is disposed in the cavity and grips a tube inserted in the cavity through the ring. A retainer holds the gripper ring in the body of the tube fitting. A release tool is provided for releasing a tube which is held by the gripper ring of the fitting. The release tool has a thin, cylindrical section portion which can be received about a tube held in the fitting and then inserted in the fitting to raise the gripper and release the tube.
