Abstract: The central binding for a ski with a mounting support having separated elements includes, in its lower part, pins (6,7,8,9) which are intended to cooperate with corresponding bayonet openings (12,16,20) provided within the elements constituting the support, as well as screws (40) which are intended to cooperate with screw threads (10) provided in the elements constituting the support. This support is composed of several separated elements which are mounted on the ski (21) with spaces between them. The elements each include a rigid or semi-rigid upper plate (11,14,17) and a resilient lower plate (13,15,18).
