ABSTRACT:
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 being interengaged by relative sliding movement therebetween. 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 sized for insertion into the locking slit when the anchoring tab has been folded into overlapping relationship with the main portion of the tab. The locking slit is formed so as to provide an abutment edge (38) which is engaged by a trailing edge (24) of the anchoring tab when the locking tab has been inserted into the locking slit, the arrangement being such that the engagement is effective to maintain the panels locked together either when the anchoring tab remains in its folded overlapping relationship with respect to the main portion or when the anchoring tab moves out of said overlapping relationship into a more upright attitude.
