Claims

[Scope of utility model registration request]

A cylindrical receiving seat part and a recessed part are formed around this receiving seat part in the middle of the hole of the joint main body part which has a hole part inside which becomes a fluid flow path, and a recessed part is formed around the receiving seat part. A female thread is formed on the inner surface of the hole located on the side, and a bellows-shaped flexible tube is inserted into the hole and is crimped onto the outer surface of the hole so that its tip abuts against the end surface of the receiving seat. A ring-shaped packing and a retaining ring that engages with the trough of the flexible pipe and can be contracted and expanded in diameter are arranged side by side, and are further screwed into the female thread so that the tip abuts the retaining ring. A tightening member is provided, and by tightening the tightening member, all of the plurality of peaks on the distal end side of the flexible tube in the valley where the retaining ring is fitted are crushed, and are pressed into contact with the end surface of the receiving seat portion. A joint device for piping configured so that a gasket is also pressed by a retaining ring and press-fitted into a recess, and at the same time comes into pressure contact with the tip of the crushed flexible pipe.
