Abstract: A ski safety binding has a ski boot clamping member on a ski and a means for locking the member. An electric release for the safety binding comprises means for detecting a force on the skier's leg and for producing a signal as a function of this force. The release also comprises a threshold circuit and means electrically controlling the locking means. The latter is operated to release the locking mechanism when the threshold circuit emits an output signal. A circuit for increasingly attenuating the output signal the shorter its duration is interposed between the detecting means and the threshold circuit.
