Abstract
The invention relates to a device for removably fixing a mask in the form of a rectangular frame, on the legs of which clamping means are provided for gripping the end of the mask. According to the invention, the clamping means comprise a plurality of individual spring elements which grip closely adjacent points on the mask edge. The individual spring elements which are assigned to one leg of the frame and are embodied as leaf springs that are interconnected in a comb-type manner can be moved from a fitting position in which the frame can be fitted with the mask into a clamping position by means of a common auxiliary clamping member.
