ABSTRACT:
The invention relates to a panel (1) with connecting means (3, 4, 7, 9) which make a positive connection with a further panel (2) possible. A panel (1) comprises as connecting means laterally a groove (3) formed by two rigid flanks. One of the two rigid flanks (6) is longer than the other one. The longer rigid flank (6) comprises a recess (7). The other panel comprises laterally a tongue (4). The tongue (4) comprises on an under- or top side a lug (9). The lug (9) and the recess (7) are so arranged that the lug (9) is able to engage with the recess (7).The side of the tongue comprising the lug comprises a slope (12), so that when the panels are in the joined state, as a result of the slope (12) a spacing remains between the slope (12) and the longer rigid flank (6).The two panels may be connected to one another gluelessly without the exertion of force.
