Abstract: The invention relates to a binding for a boot on a ski, including a toe-piece, a connection member having a front end secured to the ski and a rear end, the connection member being provided with a hook-engagement structure, a rear base adapted to be attached to the ski and a hooking mechanism associated with the rear base. The hooking mechanism includes a gripping member which is movable with respect to the rear base and is capable of moving into a first position in which it engages the hook-engagement structure of the connection member so as to limit a vertical movement of the rear end of the connection member, and a first return member exerting a force on the gripping member so as to move the latter toward the toe-piece. The binding also includes a heel-piece connected to the rear portion of the connection member. The longitudinal position of the heel-piece in relation to the connection member is adjustable.
