Abstract
A ventilator housing with at least one protective screen for covering a ventilator positioned in a housing, whereby through-hole borings for fastening the protective screen with fastening elements are provided in the walls of the housing. The fastening elements are formed as pin-shaped fastening studs, which can be inserted into the through-hole borings of the housing walls, and which have, on their peripheral surfaces, tongue-like springy counter-hooks which are directed in the direction opposed to the direction of insertion of the stud, being angularly to the longitudinal axis of the stud, so that after insertion of the studs into the borings, at least one counter-hook engages the housing wall under prestressing.
