A coupling device (40) comprising a plurality of fitting protrusions (16) protruding in the axial direction from a plurality of positions in the circumferential direction at the end portion (14b) of an annular coupling body (14), wherein each protrusion is provided, at the end portion thereof, with a latching hook (18) in one circumferential direction. The coupling device has the coupling body and the fitting protrusions formed independently of each other and includes a securing structure (42) for securing the plurality of fitting protrusions to the plurality of positions at the end portion independently of the coupling body and the fitting protrusions. The securing structure has an inward tapered surface (42a) secured to the plurality of fitting protrusions removably to the axially opposite side to an outward stretch (14d) on the outer circumferential surface of the end portion on the outer circumferential surface after the inner circumferential surfaces (16a) of the plurality of fitting protrusions are mounted contiguously to the outward stretch (14d) and securing the plurality of fitting protrusions to the predetermined position on the outer circumferential surface while fitting to the outward tapered surface (16d) of each fitting protrusion, and includes a cut (42c) for exposing the outward tapered surface of at least one fitting protrusion. |
