A safety toe unit for a ski binding comprises a base body (11) which is to be secured to the ski, with a sole holder (13) which holds an inserted ski boot from above and from the sides being upwardly pivotally mounted on the base body about a transverse axis (12). The transverse axis (12) is preferably arranged in the front end region and in particular in the lower region. The sole holder carries two side jaws (17, 18) which are laterally outwardly pivotable about vertical axes (15, 16) disposed on both sides of the central longitudinal axis (14). A release spring (20) is housed in a hollow chamber (19) of the sole holder (13) and extends substantially in the direction of the central longitudinal axis (14). The release spring (20) generates, via a lever and cam track mechanism, a holding force for the inserted ski boot which biases both the side jaws (17, 18) and also the sole holder (13) towards the ski boot holding position. The side jaws ( 17, 18) are acted on, via two control levers which are journalled on the sole holder (13) about respective vertical axes (21, 22) and via a common yoke member (25) by one end of the release spring (20) which is braced at its other end on the sole holder (13). The release spring (20) also acts via the yoke member (25), after overcoming a clearance (26) which lies within the scope of different sole thicknesses of the ski boots to be inserted, on a hold-down cam (27) which is displaceably journalled in the sole holder (13) in the direction of the central longitudinal axis (14). This hold-down cam cooperates with a cam track (28) on the base body (11) which rises obliquely from the rear to the front.
