Abstract
A panel comprises a panel body extending in a longitudinal direction and a transverse direction, a retaining groove extending in the transverse direction in an end short side of the panel body, and a locking element which is inserted in the retaining groove substantially immovably. For an extension bof the retaining groove in the transverse direction relative to a nominal width B of the panel body between a first edge extending in the longitudinal direction and a second edge of the panel body extending in the longitudinal direction, the following applies: 0.50≤b/B≤0.97. An unbreakable and leak-proof panel having good and material-friendly locking is made possible by the retaining groove which extends over only a large portion of the short side and by the locking element immovably received in the retaining groove.
