Sole-holder ski binding

The invention relates to a sole-holder ski binding having a clamping bar which is mounted on a jaw provided with sole pins, acts on the projecting front edge of the boot sole tip and is formed by a leaf spring which can be swivelled about an axis running transversely to the longitudinal axis of the ski between a locking position retaining the ski boot and a release position. In order to allow simple and reliable opening and closing of the sole-holder ski binding whilst simultaneously simplifying the design, the leaf spring is mounted on a bearing pin arranged at the front part of the jaw and can be swivelled counter to spring force into its locking position by means of a thruster which is arranged swivellably on the jaw above and behind the bearing pin and acts by means of a cam on the top side of the leaf spring in such a way that the cam retains the leaf spring in its locking position in the closed position of the thruster. Furthermore, a release lever is provided for swivelling the thruster out of the closed position.
