<p>A tongue (30) adapted for being received in a sidewardly open groove (40) of a building panel. The tongue (30), which is of an elongated shape, is intended to lock into a tongue groove (20) of an adjacent building panel. The tongue, when received in the sidewardly open groove (40), is bendable in a plane substantially parallel with a main plane of the panel, such that the tongue is at least partially resiliently displaceable in said plane. The tongue is asymmetrical in the longitudinal direction.</p> |
