Abstract: A support structure for non-progressive modular wall systems includes a panel retaining clip and channel-shaped stud formed for positive interlocking engagement. The clip is made of spring steel and is formed with several fingers which are adapted to be pressed over a flange portion of the stud. The fingers which contact the interior surface of the stud flange are formed with one or more forwardly extending projections. These projections form barbs which are securely captured behind a bead on the stud flange when the clips and attached wallboard are pressed into place.
