Hinge reinforcement (10), for a motor vehicle door hinge, has a shape corresponding to the shape of the hinge bracket (6) and is able to be joined to the hinge bracket. The first end (11) of the reinforcement (10) facing the hinge pin (5) is provided with a fork-like shape so that it can be placed against the hinge pin (5) from below the bracket onto the hinge pin between the bearing arms (9) of the bracket, and on its side facing the bracket a cam (12) engages a recess (13) of the hinge bracket (6) to prevent the hinge reinforcement (10) from falling out. The second end (14) of the reinforcement is connected to the hinge bracket (6) by a fastening element.
