A tube joint for annular corrugated tubing includes a body having a sleeve for receiving the end of an annular corrugated tube; at least one circumferential raised lobe on the sleeve for engaging an annular corrugation of the tube; and a collar for engaging the body and including a swaging section having a first camming surface for compressing the lobe radially inwardly to engage a corrugation of the tube.

Tube joint for annular corrugated tubing

A connector set adapted for releasably connecting a gas conduit from a gas appliance or the like to a gas line to provide gas to the appliance. The connector set comprises a nipple adapted to be connected to the gas conduit and a receptacle adapted to be connected to the gas line. The receptacle has a socket adapted to receive the nipple, and first and second valves. The valves are each operable between an open position and a closed position and arranged so that gas can pass from the gas line to the socket only when both valves are in their open positions. The receptacle further includes a mechanism for operating the second valve as the first valve is operated so that the second valve opens when the first valve opens and closes when the first valve closes. The first valve is operable only when the nipple is in the socket, and the nipple is removable from the socket only when the first valve is in its closed position.
