A simple lockup device for a sign having a square tubular extrusion for a post with grooved webs extending midway up the length of the interior of T-section sidewalls of the same, one sidewall web being slotted through its groove partially down from the top of the post for receiving the flange of a sign panel installed in interlocking relation therewith. A locking key bent of a rectangular strip of sheetmetal engages a vertical slot in the top of the panel flange at its middle and at its conjugate ends engages with the grooves in the webs on adjacent sidewalls of the post. A closing cap inserts four depending lugs in four corners of the top of the post in mounting on top of the same.
