SUBSTANCE: invention relates to machine building. Safety connecting device includes drive and driven parts equipped, respectively, with primary means of torque transfer and secondary means of torque transfer. The safety connecting device also contains sensitive to torque disconnection means intended to disengage the front toothed rims of the primary and secondary means of torque transfer, this results in interruption of the torque transfer, when the torque transferred between two part of the connecting device exceeds the set maximum value.
