Claim:
A quick-connect coupling for a gas line, the coupling comprising: a socket member for connection to a gas line; a nipple for connection to an gas appliance, the nipple being engageable in the socket member for coupling the gas line to the appliance; a sleeve displaceable between a locking position for securing the nipple in the socket member and a released position in which the nipple is free to be uncoupled from the socket member; a locking member displaceable into an extended position in which the locking member retains the sleeve in the locking position; a gas valve for controlling gas flow through the socket member; and a control knob connected to the gas valve and rotatable for opening and closing the gas valve; the control knob having an abutment portion movable into the path of movement of the locking member for retaining the locking member in the extended position; and the control knob having an opening in the abutment portion and the opening being dimensioned to allow sliding displacement of the locking member from the extended position and into a retracted position to release the sleeve from its locking position on rotation of the control knob into a valve-closed position.
