A panel interlocking device for joining a first panel and a second panel, the panel interlocking device comprising:
- a male tab on the first panel;
- and
- a female tab having opposing side edges on the second panel,
- wherein each of the opposing side edges of the female tab is formed entirely by a cut line, so as to separate the female lab from the second panel along each of the opposing side edges, such that each of the opposing side edges of the female tab formed by ne is concavely curved as viewed from outside of the female tab.
A panel interlocking device for securing together a first panel and a second panel in overlapping relationship, said panel interlocking device comprising:
- a locking tab struck from the first panel, and
- a retaining tab defining a locking aperture struck from the second panel,
- wherein the retaining tab is displaced out of plane of the second panel to receive the locking tab through the locking aperture to be engaged therewith,
- wherein at least one of the locking aperture and the retaining tab has opposing side edges that extend in a direction substantially parallel to free side edges of the first panel or the second panel,
