Said sections ( 18 a) can be engaged with a part ( 6 ) of the frame and held on the spring arms ( 18 ) in an elastic manner in such a way that they can be displaced in relation to the adjacent section of the periphery of the cover ( 10 ) at an angle smaller than a right angle. The invention is characterised in that a blocking device ( 40 ) is used to block the displacement of the engaging sections ( 18 a) as required.
