An electric latch for a door leaf of a motor vehicle, said latch including: - a pivoting bolt intended to cooperate with a striker, - a pawl pivoting between an open position and a closed position of the latch, said pawl being subjected to an elastic return which urges it toward said bolt, and being capable of cooperating with said bolt to prevent a rotation of said bolt in the closed position of the latch, - a driver pivotally secured to said pawl, - a retaining member capable of retaining the driver-pawl set (7, 5) in a position deviated from said bolt in the open position of the latch enabling the rotation of the bolt, the retaining member being subjected to a bistable elastic return so as to be urged by the latter either toward a stable active position for retaining the driver-pawl set (7, 5) to ensure the retaining of said pawl in the position deviated from said bolt, or toward a stable rest position in which the retaining member is held set-back from the driver-pawl set (7, 5) preventing a cooperation between the retaining member and the driver-pawl set (7, 5), - an actuator for opening the latch, - a tilting means capable of cooperating with a first active face of the retaining member to make the retaining member tilt from the stable rest position to the stable active position, characterized in that the tilting means includes at least one crank-pin (66, 68) carried by a control wheel of said actuator, the crank-pin (66,68) being capable of cooperating with the first active face of the retaining member, in that the bistable elastic return includes a bistable coil spring whose first end is fastened to the retaining member and whose second end is held in position, in that the retaining member has a general shape of a two-armed lever (41, 43) each hinged on a common axis, and in that the crank-pin (66, 68) is a through crank-pin and the through end is capable of cooperating with said driver to drive the driver-pawl set (7, 5) toward the open position of the latch. - a pivoting bolt intended to cooperate with a striker, - a pawl pivoting between an open position and a closed position of the latch, said pawl being subjected to an elastic return which urges it toward said bolt, and being capable of cooperating with said bolt to prevent a rotation of said bolt in the closed position of the latch, - a driver pivotally secured to said pawl, - a retaining member capable of retaining the driver-pawl set (7, 5) in a position deviated from said bolt in the open position of the latch enabling the rotation of the bolt, the retaining member being subjected to a bistable elastic return so as to be urged by the latter either toward a stable active position for retaining the driver-pawl set (7, 5) to ensure the retaining of said pawl in the position deviated from said bolt, or toward a stable rest position in which the retaining member is held set-back from the driver-pawl set (7, 5) preventing a cooperation between the retaining member and the driver-pawl set (7, 5), - an actuator for opening the latch, - a tilting means capable of cooperating with a first active face of the retaining member to make the retaining member tilt from the stable rest position to the stable active position,
