Assemblies of sheets of corrugated plastic board and molded plastic interlock elements providing useful products such as containers. Sheets of corrugated plastic board are interlocked with one another by means of molded plastic connector pieces or strips having receptor slots containing spaced lock ramps. The slots receive a uniform edge of a sheet of corrugated plastic which is provided with spaced slits aligned with the spaced lock ramps. Entry of the sheet edge into the connector slot causes the spaced lock ramps to compress the edge until the aligned slits pass thereover, and the "memory" of the corrugated plastic board causes the edge portion thereof, beyond the slit, to spring back to its original thickness and thereby lock the edge of the plastic board within the slot of the molded plastic connector.
