an area on a front side of the intermediate location of the arm body that is coupled to the leg defining a lock and an area on a rear side of the intermediate location of the arm body that is coupled to the leg and substantially opposite to the front side defining a releasing portion; and
in a process of connecting the housing body to the mating housing, the area on the first side of the intermediate location of the arm body initially deflects away from the reference surface and then resiliently returns so that the lock locks a mating lock on the mating housing, whereas the releasing portion is displaced toward the reference surface for separating the lock from the mating lock and releasing a locked state with the mating lock when the arm body is inclined with the leg defining a support, and wherein
the leg is inclined forward from the reference surface toward the arm body.
