The invention relates to a cover for a swimming pool that is composed of individual mechanically interlinked elements. When the swimming pool is used, said cover rests on the bottom of the swimming pool. A buoyancy can be generated for the cover so that the cover floats on the water surface of the swimming pool when the latter is not used. The aim of the invention is to provide a cover that is reliable and safe. To this end, the individual elements are sealed hollow elements (1) that include at least one cavity (2) whose volume can be modified in such a manner that either a buoyancy in the direction of the water surface of the swimming pool or a descending force in the direction of the bottom of the swimming pool is generated.
