<p>The invention provides a tensioning buckle for a strap-like pull element on ski boots or the like. The buckle comprises a tensioning lever hinged for pivoting movements about a hinge axis located within a base plate intended to be fixed on a boot or on an element connected to a boot. The device further comprises two arms which are adjacent to the hinge axis and distant from each other by a clearance equal at least to the width of the pull element and allowing between them a passageway for the pull element, and furthermore the device is provided with a clamping device for holding a pull element. The buckle is characterized in that the tensioning lever, in the portion opposite to the hinge axis, is provided with a clamping lever and a cover plate for covering the pull element. The clamping lever is pivotally mounted in the tensioning lever, its pivotal axis being substantially parallel to the hinge axis of the tensioning lever, and its free end being located in a direction opposite to the direction in which a tensile load acting on a pull element is adapted to be exerted. The length of the clamping lever is greater than the perpendicular distance between its pivotal axis and the lower surface of the cover plate, diminished by the thickness of the pull element.</p> |
