A building panel having an edge portion presenting a sidewardly open groove, in which a tongue formed as a separate part is received, wherein the tongue is of an elongated shape and made of molded plastic,
- wherein the tongue comprises at least two protrusions at a first long edge of the tongue,
- wherein the at least two protrusions are configured to be bendable in the groove in a plane parallel to an upper surface of the tongue, the at least two protrusions extending essentially along the plane,
- wherein the tongue has a second long edge which extends outside the groove,
- wherein the second long edge is straight over portions of the second long edge directly opposite to the at least two protrusions, and
- wherein a length of each of the at least two protrusions is larger than a total width of the tongue.
The building panel as claimed in claim 4, wherein the vertical protrusion is arranged at a distal end of at least one of the at least two protrusions.
The building panel as claimed in claim 6, wherein the polymer material is reinforced.
