    • Improvements in the constitution of front jaws in safety ties for skis, in which a pivoting member is pivotable around a bolt fixed on the ski perpendicular to its surface, against the action of an elastic element, this element being elastic calculated in such a way that the foot resting across the front edge of the sole of the boot against a supporting surface of the front jaw is released by acting a torsional force dangerous to the foot, while being returned to the central position from small tilting movements caused by minor lateral forces, characterized in that the elastic element is constituted by a torsion spring made of wire, equipped with free criss-crossed legs that, behind the crossing point, distance a certain space from each other and they run substantially and mutually parallel, and because between the legs of the dock are arranged separate top is, each of which belongs to one of the two pivotable parts relative to each other, the resilient legs resting with pre-tension against said stops, when the front jaw is in the central position.
