The invention relates to a device allowing the vertical hanging up of documents established on supports made of paper, of cardboard and generally on low-thickness films. It consists of a corner post made of metal, plastic or other material in which are accommodated balls made of glass or of another material. Under the effect of gravity, the balls 1 are pushed by the sloping face of the corner-post 3 towards the vertical face 2. When the user introduces from the bottom to the top a film in the lower opening of the corner post, this film pushes the balls upwards; when the user releases the film, the balls wedge the latter against the vertical face 2. To remove the film, it suffices to pull the film downwards. The device according to the invention is intended in particular for the wall display of various information documents. <IMAGE>
