In a heel tightener for safety ski-bindings, a pusher member is movable away from the ski along the tension members against the force of at least one spring and a tightening lever is mounted to pivot about a transverse axis, the free end of the lever being engageable in the groove of the heel and pivotable upwardly into a heel releasing position. A counterbearing is provided to limit downward pivoting of the tightening lever into the clamping position. The tightening lever is secured in the clamping position by locking means which are released after movement of the pusher member by a predetermined distance away from the ski. The locking means comprise a lever arm linkage disposed between the pusher member and the tightening lever axially parallel to the latter, and a locking lever for the bell crank lever, which locking lever is pivotably mounted in the pusher member against the action of spring force.
