A safety coupling device comprises a bolt or pin provided at its free end with two parallel and diametrally extending bores (3.1) spaced apart in the axial direction of the bolt, and two securing pins (5) each provided with a head plate (5.1) and insertable into the bores (3.1) from opposite directions. The free end of each pin (5) passes through an opening (5.2) in the head plate (5.1) of the respective other pin (5), and each pin (5) is locked in place by a spring clip or plug inserted through a transverse bore (6.1) in the pin end. <IMAGE>
