PROBLEM TO BE SOLVED: To provide a joint for bellows pipe having satisfactory sealing property for a long time without affecting a packing part performing sealing action even if the vibration and a bending force act on pipes after they are connected and preventing a large leakage even in case of emergency when a fire occurs. SOLUTION: This pipe joint for bellows pipe consists of a bellows pipe forming a cylindrical pipe part having a predetermined width at a tip of a pipe to be connected and a collar overhanging outward in succession to the cylindrical pipe part, a joint main body having an end face butting against the collar, a tapered inner face narrowing inward from the end face, and an inner peripheral face for receiving the cylindrical pipe part to form a packing chamber between the cylindrical pipe part and it, a pressing ring having a pressing part screw-fitted in the joint main body to nip the collar between the end face of the joint main body and it, an elastic packing mounted on an outer peripheral face of the cylindrical pipe part and compressed in the packing chamber, and a washer mounted between the collar part of the bellows pipe and the pressing part of the pressing ring.
