Abstract: The object of the present invention that a fixing ring is provided, which has annular ring form made of strip materials and is mounted in a bore or on a outside surface of flexible joints for piping, and not only has compact form and structure but also can be adjusted stepless and fixed through wide range. An inclined plate member, which is positioned on the inner or outer surface of a strip material with a certain tapered space, is fixed at ends of inner surface side or outer surface side of a strip material in order to be fixed in overlapped situation. A roller is disposed in the certain tapered space as it can roll freely along circumferential direction. The other end of the strip material is inserted between the one end of a strip material and the roller.
