Panel interlocking means (45,46) for securing together a pair of panels (13,28) in overlapping relationship includes a locking tab (45) struck from one of the panels (12) and arranged to be driven through a locking aperture (46) struck from the other panel (28). The opposed lateral edges (45a, 45b) of the locking tab have deformable marginal portions (a) formed by cut lines (b, c) which are deformed by the opposed lateral edges (46a, 46b) of the locking aperture when the locking tab is driven through the locking aperture.
