An arrangement of building elements capable of a snap-fastening interconnection comprises an element, especially the tongue, consisting of a different material from the other building elements. An MDF/HDF panel, is initially milled along the longitudinal and/or transverse sides, and the resulting groove is then provided and/or foam-filled with extrudates. Finally, the free ends of the extrudates are milled to form the profile of the tongue. Alternatively, or additionally, a groove may also be milled into the extrudates.
