A quick-connect coupling for a gas line has a socket member for connection to a gas line and a nipple for connection to a gas appliance, the nipple being engageable in the socket member for coupling the gas line to the appliance, with 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 is displaceable along a path of movement into an extended position to retain the sleeve in the locking position. A control knob connected to the gas valve is rotatable for opening and closing the gas valve to control gas flow through the socket member. The control knob has an abutment portion movable into the path of movement of the locking member for retaining the locking member in the extended position, the control knob having an opening in the abutment portion dimensioned to allow sliding displacement of the locking member from the extended position into a retracted position to release the sleeve from its locking position on rotation of the control knob into a valve-closed position.
