Abstract: A plug as an electrical connector according to the present disclosure includes a box-shaped housing and a lock lever having an arm in such a manner that a base end of the arm is rotatable, and the lock lever is configured to pull the mating housing inside the box-shaped housing. On a side face of the box-shaped housing, a projection is provided which can be hidden from the side face thereof. A recess is provided in an intermediate portion of the arm of the lock lever, and the projection can be introduced and the rotation of the lock lever in the one direction can be prevented. The recess includes a bottom wall (first inner wall) and a side wall (second inner wall) formed therein which can be pressed by the projection by a rotational force of the lock lever in one direction being divided.
