Abstract
Abstract The present invention relates to an attachment system for forming a substantially planar wall structure, intermediate and end connectors to be used in the system, and a method of assembling the system to form the desired wall structure. The intermediate connector joins adjacent ones of the wall panels and comprises two panel retention members in an overlapping relationship. Each panel retention member has a base portion, a web portion, and two substantially parallel, non-coextensive, integral flanges defining a recess for receiving an edge portion of a wall panel.
