An improved ski binding has a resiliently-loaded holding device operatively interposed between a boot assembly and a ski to provide points of contact between the boot assembly and ski at each of three mutually-spaced locations arranged at the apices of an imaginary triangle. At each location, a convex member is mounted on the boot assembly to engage a concave surface on the ski. An improved pivot clip is mounted on the ski and provides two of the concave surfaces. The pivot clip has two cam surfaces, each of which is engaged by a convex member mounted on the sole-plate. Each of the cam surfaces is inclined in a direction such that an external moment applied to the boot assembly about the skier's tibial axis will produce a reaction force between one cam surface and its associated convex member, which reaction force will have a longitudinal component not opposing the applied moment.
