In a safety ski binding, a heel hold-down device has a heel retaining member urged by spring means to its heel retaining position and is pivotally mounted by means of a pair of lateral arms extending upwardly and rearwardly from a transverse horizontal axis, these lateral arms having their upper ends interconnected by a shaft extending through the retaining member, this shaft being rigid with a bow-shaped element of which the central section normally bears against the ski surface. Spring means constantly urge the retaining member to its inoperative position and may consist of a single steel wire coiled along lateral portions thereof formed with end loops slidably engaging the relevant lateral arms.
