ABSTRACT:
The invention relates to a panel, with a tongue on a longitudinal and a transverse edge, projecting beyond said longitudinal or transverse edge, with essentially parallel tongue surfaces and a groove on the opposing longitudinal or transverse edge, enclosed by lateral panel sections, corresponding to the tongue of an adjacent panel with essentially parallel groove edges. In order to lock two adjacent panels such as to run into each other, a projecting locking element is provided on at least one tongue surface at least in parts and in each region of (a) panel section(s) corresponding to said locking element(s) for connected panels a recess(es) is provided, whereby the region (B) of the tongue with the locking element and/or at least one of the regions of the tongue and the panel sections which are in contact on introducing the tongue into the groove, before the locking element clips into the recess, have an elastic embodiment such that said elasticity is greater than the elasticity of the locking element.
