Claims

[Scope of utility model registration request]

When attaching the tube end ring 1 to the outer end of the pipe 4, a groove 2 of an appropriate shape is provided on the inner surface of the tube end ring, and an O-ring-shaped sealing material 3 made of rubber or the like is placed in a part of the groove. The sealing material is inserted into the outer surface of the pipe, and the pipe is expanded from the inner surface of the pipe using a roller-type tube expander 5, etc. to plastically deform the pipe, the outer surface of the pipe is bitten into the groove of the pipe end ring, and the sealing material is inserted into the pipe. The tube end is compressed and fixed between the outer surface of the tube and the tube end ring.
