A retainer (33) comprises a gasket holder (72) for holding the outer periphery of an annular gasket, and a coupling member holder (73) for holding an end portion of a coupling member. The coupling member holder comprises two elastically deformable lugs (73a) projecting axially of the retainer for holding the coupling member. The retainer has handle pieces elastically deformable radially inwardly of the retainer to thereby elastically deform the coupling member holding lugs radially inward. |
