A butt joint consists of a lock casing (1) in the first stake, a gudgeon (2) in the second stake and a transverse lock device (3) that extends through the lock casing (1) and the gudgeon (2). The lock casing (1) is formed by the end of the reinforcement rod (5) by ending this in a receptacle form and the gudgeon (2) is formed by the end of the reinforcement rod (5) by ending this so that it flattens out on the sides. The butt joint can hereby be produced by a simpler procedure than previously.<IMAGE> |
