<p>The frame (10) has frameworks (24) and an intermediate piece (26), where the frameworks are formed for providing the mutual connection with form-fit interference recesses (30) and projections (32) at opposite corner edges. The end piece inserted on the end-sided corner edges covers the end-sided recesses and projections. The recesses and the projections are covered by the intermediate pieces that are insertable on the individual frameworks adjacent to edge areas and lockable in the interference position.</p> |
