The lock for a motor vehicle opening leaf comprises a wheel (RD) intended to be driven in rotation about an axis (A1) under the action of an electric motor, said wheel driving in rotation a wrist pin (MT), said wrist pin (MT) collaborating with a member for opening said lock so as to move it from a rest position to an open position upon rotation of said motor. In this lock, the wrist pin (MT) is secured to a plate (PT) which is mounted so that it can rotate about said axis (A1), and comprises a first and a second associated member for coupling the plate (PT) and the wheel (RD) in terms of rotation, said first and second members comprising a drive peg and an associated groove (RO) in the form of an arc of a circle, so that said wrist pin (MT) is free to turn about said axis (A1) through a certain angle. With this arrangement, the lock can be opened manually when its motor fails.
