The sidewalls (3,4) have cutouts (5-7) in them, running in a straight line and extending over their full height. One sidewall may be interrupted by its cutout and divded into two part side walls (3a,3b) at an interval apart, while the opposite one is formed by cutouts corresponding to this interval, in width.
