A clip (60) is mounted in a housing (11) of a charging connector (10). The clip (60) includes a box-shaped main body (61) formed by assembling two half members (62, 62). The main body (61) is prevented from moving in longitudinal and circumferential directions of a wire (W) relative to the housing (11) by the surface contact of the outer surface of the main body (61) with the inner surface of the housing (11). Wire insertion holes (67) are formed in the main body (61) by assembling the half members (62, 62) so that pairs of curved portions (66, 66) face each other. The wire (W) is held in the main body (61) by being tightly held by the curved portions (66, 66).
