PROBLEM TO BE SOLVED: To provide an assembling method for a device for preventing coming-off of a fluid pipe capable of securely connecting fluid pipes to each other in a water-tight state in which each arc-shaped lock piece can be set without adding excessively large local force when set to prevent it from coming off, and in which the arc-shaped lock pieces deeply and uniformly bite the outer form of the fluid pipe when it starts coming off. SOLUTION: An outer circumferential center of the arc-shaped lock piece 6 is pressed by a pressure bolt 10 with prescribed pressure. A lock claw 6a on an inner circumference of the arc-shaped lock piece 6 has a radius of curvature smaller than a radius of curvature R of the outer circumference of an insert port end part 2a of the fluid pipe when assembled. It is set in such a way as to bite the outer circumference of the insert port end part 2a when it starts coming off. Local stress is not added to the fluid pipe. Coming-off preventing effect is effectively achieved. Peeling of an inner lining from an inner surface of the fluid pipe is prevented. COPYRIGHT: (C)2004,JPO&NCIPI
