<p>A connector (1) includes a temporary lock member (60) having a mating arm (61) provided at a connector housing (2) and an arm mating hole (62) provided at a cover body (11) of a connector cover (10). The mating arm has an edge portion formed with a protruding portion (61a). The arm mating hole is so configured that: in a position where the protruding portion abuts an interference inner wall face (62a), the cover body is pressed inward while being rotated such that the cover body returns to a position where the cover body faces an inherent mounting direction of the cover body, which allows the protruding portion to get over the interference inner wall face and to be inserted to an insertion completion position; and in the insertion completion position, the arm mating hole sandwiches the protruding portion.</p>
