Abstract

A protective hood (1) for a right-angle grinder having a tightening device, which has a tightening band (4) firmly connected to the protective hood (1) for a right-angle grinder, the two ends (5, 6) of the tightening band being embodied as a first and second eyelet (7, 8), so that they form a first and second abutment (9, 10) 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 (2), which with its first end (15) can be supported in the first eyelet (7) pivotably about a first axis (9a) 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 (3), which can be connected movably to the tightening lever (2), the spring (3) being pivotably supported about a second axis (11) in the tightening lever (2) that does not coincide with but is parallel to the first axis (9a), and the spring (3) can be connected to the second eyelet (8) of the second end (6) …
