An electrical connector comprises a first connector, a second connector matable with the first connector, an elastic clip mounted on the first connector and movable between an engagement position and a disengagement position, and a safety locking member slidably mounted on the first connector and movable between a pre-locking position and a locking position. The elastic clip is coupled to the second connector in the engagement position to keep the second connector mated with the first connector. The elastic clip enables decoupling of the first connector and the second connector in the disengagement position. The safety locking member contacts the elastic clip in the locking position and prevents movement of the elastic clip from the engagement position toward the disengagement position.
