A covering system comprising a rectangular covering element (1) having a first covering surface (2a) and a second covering surface (2b). In edges (3) connecting the first and the second covering surfaces (2a, 2b) there is arranged a groove (4) whose depth is A. The groove (4) has a recess (5) whose depth is X in the depth direction of said groove (4) and length is Y in the direction of said edge (3), and the distance of the recess (5) from the nearest corner of the covering element (1) is Z. The covering system further comprises a fixture (6) which is to be arranged in the covering element groove (4) and whose thickness T is at most equal to the width of the groove (4), the fixture (6) having two projections (10) perpendicularly to the thickness T, the distance between the projections (10) from the symmetry axis (18) of the projection being at least substantially Z - A. The shape of the projection (10) is arranged suitable for providing a substantially clearance-free shape connection in the groove recess (5). |
