ABSTRACT:
The invention relates to a strip for a building board (2), exhibiting a board body (S) which is formed with a gripping stud (24). The strip (10) extends from the body (S) and from which are formed gripping elements (26, 28), which are bent round the gripping stud (24) for mechanical fastening of the strip (10) to the body (S), as well as a locking element (12) for enabling mechanical joining of the board (2) to similar boards.
