Abstract
A clamping device for clamping a protective hood on a clamping collar of an angle grinder has, a clamping strap which has ends and is clampable together in the region of the ends, a clamping lever having one end and being pivotable at the one end about a pivot axis in respect of one of the ends of the clamping strap, and a transmission member which is engaged by the clamping lever and which engages at a distance from the clamping lever another of the ends of the clamping strap and during clamping brings the ends of the clamping strap nearer to one another. The transmission member, the clamping member, and the ends of the clamping strap form a toggle-lever device which during clamping contracts the clamping strap in the region of the ends of the clamping strap in a manner essentially free of any bending moment.
