A protective hood ( ) for a right-angle grinder having a tightening device, which has a tightening band ( ) firmly connected to the protective hood ( ) for a right-angle grinder, the two ends ( ) of the tightening band being embodied as a first and second eyelet ( ), so that they form a first and second abutment ( ) and can be connected to one another under tension by means of at least two tightening elements, the first tightening element being a tightening lever ( ), which with its first end ( ) can be supported in the first eyelet ( ) pivotably about a first axis ( ) and which can be brought into a first position in which the tightening device is not tightened, and into a second position in which the tightening device is tightened, becomes capable of being produced at less expense with still high quality by providing that the second tightening element is a spring ( ), which can be connected movably to the tightening lever ( ), the spring ( ) being pivotably supported about a second axis ( ) in the tightening lever ( ) that does not coincide with but is parallel to the first axis ( ), and the spring ( ) can be connected to the second eyelet ( ) of the second end ( ) of the tightening band ( ), and the spring ( ), on its end that can be connected to the second eyelet ( ), has a straight region that is embodied as parallel to the second abutment ( ).
