PURPOSE: A structure for connecting a high-pressure gas supply pipe is provided to firmly join a connecting member and a pipe by pressing the outer circumference of a pipe by stopping projections of the connecting member so that high-pressure gas passing through the gas supply pipe passes through the pipe. CONSTITUTION: A structure for connecting a high-pressure gas supply pipe comprises a connecting member(10), a pipe(20), and a gas supply pipe(30). Stopping projections(11) are protruded to an inner lower direction of the inner circumference of the connecting member and symmetrically formed. Screw-threads are formed in the lower part of the connecting member. The pipe is inserted by being closely adhered to the inner circumference of the connection member. The gas supply pipe is thread-joined to the screw-threads from the lower part of the connecting member. The gas supply pipe is inserted closely to the pipe and joined to the connecting member by welding.
