Claims19
A tongue for connection of a building panel, said tongue is of an elongated shape and made of moulded plastic, the tongue comprising at least two protrusions at a first long edge of the tongue,
- wherein the protrusions are bendable in a plane parallel to the upper surface of the tongue and extend essentially in the parallel plane,
- wherein the tongue has a second long edge, which is essentially straight over substantially the whole length of the tongue,
- the tongue further comprising a gluing part configured to be glued into a groove at an edge of the building panel,
- wherein the gluing part is an edge section of the tongue, the edge section spaced from the protrusions in a length direction along the first long edge of the tongue such that at least one of the protrusions extends in a direction from the first long edge toward the gluing part, and
- wherein at least one of the protrusions is provided with a flexible link that connects the edge section to a body of the tongue.
