In order to secure the wall elements to the framework in an manner invisible from the outside, projecting hook elements are fixed on the inner side of the wall elements, matching hook elements can be hooked into said projecting hook elements and the matching hook element can be mounted on the framework stays so that the hook elements may be hooked onto them.
