Abstract: A signage clamp for supporting a sign from a retail display rack having a rod has a rectangular expandable saddle-like jacket having a top wall and opposing side walls with lower edges. Each edge has at least one opposing catch with a tab extending outwardly therefrom. The jacket is guidable over the rod with the tabs forcing the catches outwardly and expanding the jacket as to capture the rod afterwhich the catches secure the jacket to the bar. The tabs may be moved apart to release the jacket from the rod. Support means are on the jacket for supporting the sign on one of the display racks at the point-of-purchase.
