Abstract: A ski brake including at least one brake arm is detachably associated with a ski binding. The brake arm is arranged for movement about a transverse pivot axis defined by pivot axle means located between a base plate of the binding and a heel plate for supporting the heel of the ski boot. The heel plate can be clipped into position on the base plate, with or without the ski brake present, by means of cooperating clip elements on the base plate and heel plate respectively. Three different embodiments are shown including a base plate mounting which allows the ski to flex freely and an arrangement for a ski brake having two transverse pivot axles interconnected by a torsionally loaded actuating loop.
