PROBLEM TO BE SOLVED: To provide a gas filled coupling having compact construction permitting quick separating operation after supplying gas without giving the pressure influences of high pressure gas to a valve portion and requiring labor hours for pressure eliminating operation. SOLUTION: The gas filled coupling comprises a coupling body 52, a joint part 56 provided at one end of the coupling body 52 and adapted to be connected to a receptacle, a main valve 62 slidably provided in the coupling body, a piston 78 for sliding the main valve 62 in the axial direction to open/close a gas supply passage, a remaining pressure opening valve 66 provided at the other end of the main valve 62, and a valve seat 98 communicated with a pressure eliminating passage provided in the remaining pressure opening valve 66 in its moving direction.
