A receiver for a sign panel having a vertical rib defines upper and lower spaced-apart internal cavities, one of which receives the vertical rib and the other of which receives a vertical support from a sign stand, for example. A catch extends into the upper cavity so as to engage the rib. The invention finds particular application with sign panel supporting ribs which have plastic pockets fitted thereto to reduce wear and tear on the rib end.
