ABSTRACT:
The invention relates to a protective hood for a portable tool with a rotary tool, having a clamping device designed as a clamping ring for fastening to a machine neck of the portable tool, and having an anti-rotation locking means for fixing the angular position of the protective hood relative to the portable tool. It is proposed that at least one rotation-locking element (19) which can interact with a rotation-locking element (19) of the machine neck be arranged in a fixed position on the clamping ring (7) for forming the anti-rotation locking means. A portable tool having such a protective hood (1) is also proposed.
