The display unit can accommodate at least two opposite edge sides of a sign and comprises elongate bars with identical cross sections couplable to one another at right-angles. Each bar has a hollow profile with a longitudinal slot, and the coupling piece for the bars comprises partly a section insertable in one of the profiled bars, and partly a piece joined to the first part via the slot and insertable in the end of another bar. The coupling pieces are moulded in one piece from pliant material, and fixed in position by spring effect.
