Abstract: A display having a modular element structure, including a tubular upright provided with a base and having at least one recess, pointed in at two longitudinally separate portions embracing the upright, each of the portions being provided with a projection complimentary to the recess, a threaded band of one portion meeting with a threaded band of the other portion when these are combined to form the collar, and then outwardly projecting lower band. The display also includes a tubular sleeve mountable over the collar from above and resting on all of the projecting band via a complimentary portion, the height of the sleeve being such as to leave the threaded band upwardly free, a plurality of beams fixed at least one end and an end piece which is provided with a device for hooking it to the tubular sleeve, and the ring nut which screws on to the threaded portion of the collar positions it so as to lock the end piece of the beam to the sleeve.
