<p>An arrangement for securing together a pair of panels (10,12) comprising a locking tab (14) projecting from an end edge (16) of one of the panels (10) and a locking slit (28) provided adjacent an end edge (12a) of the other of the panels (12) the locking tab and the locking slit are interengaged by relative sliding movement. The locking tab includes an anchoring tab (20) hinged to one side edge of a main portion (18) of the locking tab and the locking tab is sized for insertion into the locking slit when the anchoring tab has been folded into overlapping relationship with the main portion of the tab and the locking slit is opened by displacing a foldable edge strip into an upright position. This upright face of the edge strip is engaged by a trailing edge (24) of the anchoring tab when anchoring tab unfolds into an upright position after the locking tab has been inserted into the locking slit.</p> |
