Abstract

The invention relates to panels (1, 2) that can be interlinked without using glue. In the interlinked state of the panels, a cord (3) runs along the upper side of and between the panels. Said cord widens downwards and rests on the upper side of a spring (5) that forms the coupling element of a panel. The widening is preferably asymmetric. The inventive panels especially allow to provide a wall covering or a ceiling covering in an especially simple manner. The cord consists of a compressible material and prevents water from entering the gap between the panels. The design also compensates for effects related to expansion and shrinkage.
