Abstract
Abstract Corrugated panels are intercoupled by a male and a female connector, each having a part received in its respective panel. The female connector has a U-shaped receiving volume, with a receiving slot in the front portion. The male connector has a pair of flanges connected by a rib. When assembled one flange is inserted in the receiving volume, and the rib is in the receiving slot. Two female connectors can be mated, by inverting one and inserting a part of its front portion into the receiving volume of the other female connector.
