Abstract

The invention is based on a protective hood fastening device having a fastening element (12a-12n) for fastening a protective hood (14a-14n) which is intended for partly enclosing a rotating application tool on a body (16a-16n) of an electric tool (10a-10n). It is proposed that the fastening element (12a-12n) comprise at least one latching element (18a-18n) for locking the protective hood (14a-14n) against rotation relative to the body (16a-16n) of the electric tool (10a-10n).
