The pin (1) has an axial hole partially designed as a threaded hole in an end section for receiving a threaded pin (3), and as a free hole in another end section. The free hole has a smaller diameter than that of the threaded hole. The latter end section is provided with an axial slot. The threaded pin includes thread-free extension, which includes a diameter smaller than that of a threaded section of the threaded pin and larger than that of the free hole. The thread-free extension includes a conical attachment at a free end. Stoppers (9) protrude from an outer surface of the pin. |
