The invention relates to a method and a device for uniting two board-shaped elements (for example, 4a, 2b) at an angle to one another. The board-shaped elements (4b, 2b) have co-ordinating slots (for example, 4b2, 2b1; 4b3, 2b2) incorporated into them, the width of which in each element corresponds to the thickness of the other element. The slots are inserted into one another in order to unite the elements. At least one of the slots (for example 2b1; 4b3) is designed to narrow slightly from its mouth so that a self-locking effect is achieved. |
