The handle (100) has arms (200, 300) assembled by a hinge (110) and moved between unfolding and folding positions. A head (210) is equipped with a pivot (218) and assembled by an axle (212) at an end of one of the arms. The pivot is rotatably mounted in a retaining plate fixed on a frame (D). A rod (310) is assembled by an axle (314) at an end of another arm. The rod is joined to a clevis (320) associated with a hinge element on a leaf. An axis of the pivot is located in a plane same as the latter axle and shifted from the latter axle in the folding position of the arm.
