A structure for a use in either an anti-crossing device for skis or a ski brake. A torsion spring is utilized to urge a projection member to an upright position on the ski. In the anti-crossing device for skis, the resilient projection member will prevent movement of a ski to the crossed position in one direction while simultaneously permitting movement of the ski in the opposite direction by flexing the resilient projection downwardly onto the upper surface of the ski. In the ski brake environment, the ski boot effects a resilient flexing of the projection member down onto the upper surface of the ski when the ski boot is mounted between the ski bindings. The resilient projection member has extension members which project below the lower surface of the ski when the resilient projection member is in the upright position.
