    Abstract: The invention relates to a safety tile, including a tile body of rigid material, such as concrete, and a cover plate provided with an enclosing edge and being of an elastically flexible material, such as rubber. The cover plate has ribs integrally formed therewith uniformly distributed at its bottom side directed towards the tile body, of which the bottom ends hang down and rest on the upper surface of the tile body. The ribs extend diagonally across the bottom side of the plate with main diagonals extending between two opposite corners of the cover plate.
