Alpine ski binding (1) comprising a base plate (2), to which a boot position-retention element (3) and a ski brake (8) are assembled. The base plate (2) is designed to be integrally attached to the ski using screws (14, 15). The ski brake incorporates a seating (10) superposed to the base plate (2), and the base is assembled to the base plate through the cooperation of tenons (18, 19) and mortises (20, 21) in the base plate (2). The brake (8) is, moreover, assembled to the base plate (2) by a movable locking device (23). The front screws used to assemble the binding to the ski pass through both the seating (10) of the brake (8) and the front part of the base plate (2), and their heads rest on the base plate (10) of the brake. The binding is delivered with the brake assembled, and, subsequently, dismantling the brake is possible by loosening the front screws (14) and by opening the locking device (23).
