A connector (10) includes a housing (12) having an opening (24) into which a cable (14) is inserted, and a retainer (16) is mounted on the housing (12) from the side of the opening (24). The retainer (16) includes locking lances (44) that face the cable (14) and are resiliently displaceable toward the cable (14) for holding the cable (14). The housing (12) includes cantilevered pressing portions (36). The pressing portions (36) displace the locking lances (44) toward the cable (14) to bring the locking lances (44) into contact with the cable (14) by pressing the locking lances (44) toward the cable (14). The retainer (16) includes displacement preventing portions (72) to prevent displacements of the pressing portions (36) in directions opposite to contacting directions with the locking lances (44) by contacting the pressing portions (36) in the directions toward the cable (14).
