ABSTRACT:
A [connector] device with a safety shut-off feature for [connecting a gas appliance to a source of gas] preventing the flow of a gas in the event of an occurrence which might cause gas leakage or a fire hazard. The [connector] device comprises a tubular line [, a first coupling adjacent the inlet end of the line for releasably coupling the line] adapted for connection to [the] a source of gas, [a second coupling adjacent the outlet end of the line for releasably coupling the line to the appliance,] and a valve associated with the line movable between an open position for permitting passage of gas through the line and a closed position for preventing passage of gas through the line. An electric circuit controls the operation of the valve. The circuit comprises an electrical conductor on the line designed to break or otherwise [become non-conductive] undergo a change in electrical resistance in response to excessive heating or damage to the line, thereby causing [an interruption] a change in the flow of electric current through the electric circuit. The valve is responsive to such [interruption] change to move to its closed position to prevent further passage of gas through the line.
