1. 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 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.
2. The tongue as claimed in claim 1, wherein said edge section is provided with a breaking part, configured to be broken when the tongue is inserted into the groove.
3. The tongue as claimed in claim 1, wherein said edge section is provided with an outer protruding stop part, which overlaps an inner stop part, the inner stop part protruding from the edge of the body of the tongue, wherein said inner and outer stop parts cooperate to limit the displacement of the tongue in the groove.
4. The tongue as claimed in claim 1, wherein said edge section is provided with a protruding friction connection, configured to hold the tongue in the correct position until the glue is cured.
5. The tongue as claimed in claim 1, wherein a protrusion is provided with a protruding friction connection, configured to hold the tongue in the correct position until the glue is cured.
6. The tongue as claimed in claim 1, wherein the tongue is provided with an edge section on each edge of the tongue.
7. The tongue as claimed in claim 1, wherein the protrusions are bow shaped.
8. The tongue as claimed in claim 1, wherein there is an angle between the protrusions and the longitudinal direction of the tongue.
9. A building panel provided with a tongue, according to claim 1, wherein said tongue is displaceable in a groove at an edge of the building panel.
10. 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 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, and
wherein at least one of the protrusions is provided with a flexible link that extends from a distal-most tip of the at least one of the protrusions and connects the edge section to a body of the tongue.
11. The tongue as claimed in claim 10, wherein said edge section is provided with a breaking part, configured to be broken when the tongue is inserted into the groove.
12. The tongue as claimed in claim 10, wherein said edge section is provided with an outer protruding stop part, which overlaps an inner stop part, the inner stop part protruding from the edge of the body of the tongue, wherein said inner and outer stop parts cooperate to limit the displacement of the tongue in the groove.
13. The tongue as claimed in claim 10, wherein said edge section is provided with a protruding friction connection, configured to hold the tongue in the correct position until the glue is cured.
14. The tongue as claimed in claim 10, wherein a protrusion is provided with a protruding friction connection, configured to hold the tongue in position until the glue is cured.
15. 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 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,
at least one of the protrusions is provided with a flexible link that connects the edge section to a body of the tongue, and
the gluing part is positioned more distally from a center portion of the tongue in the length direction along the first long edge of the tongue than a protrusion that is closest to the gluing part.
16. The tongue as claimed in claim 15, wherein said edge section is provided with a breaking part, configured to be broken when the tongue is inserted into the groove.
17. The tongue as claimed in claim 15, wherein said edge section is provided with an outer protruding stop part, which overlaps an inner stop part, the inner stop part protruding from the edge of the body of the tongue, wherein said inner and outer stop parts cooperate to limit the displacement of the tongue in the groove.
18. The tongue as claimed in claim 15, wherein said edge section is provided with a protruding friction connection, configured to hold the tongue in the correct position until the glue is cured.
19. The tongue as claimed in claim 15, wherein a protrusion is provided with a protruding friction connection, configured to hold the tongue in position until the glue is cured.
