Abstract: A device for the exchangeable and partial fixing of ceramic or natural stone wall and floor lining elements, such as borders, tiles, plates, and similar, on tiled faces, including a bar of substantially U-shaped cross-section which can be fastened to the wall surface between two rows of tiles, and on which the wall and floor lining elements can be detachably fastened between first and second legs extending from a U-shaped portion of the bar. The first leg is movable with respect to the second leg so that a distance between the first and second legs can be varied.
