A first one (3) of said panels has a first cutout formed in a region which overlaps said second panel (1), said second panel (1) has a second cutout which overlaps said first cutout and at least one boss (21). The screw (10) extends through an overlapping portion (23) of said cutouts, and the boss (21) engages said first cutout. Reference figure: Fig. 3</p> |
