The invention concerns a safety locking device intended to equip electromechanical equipment provided with a rotating shaft, the device comprising a first friction element connected rotationally to the said shaft, and a second friction element immobile rotationally and extending opposite the first friction element, one of the two friction elements being able to move in translation, under the action of controllable actuation means, between a locking position and a release position. In accordance with the invention, the locking and release positions correspond to successive angular positions of a selector able to move in rotation and connected in translation to the friction element able to move in translation, the said selector being maintained in any one of its angular positions by a resilient member, whilst the actuation means provide solely the passage of the selector from one angular position to the following one, and consequently passage from the locking position to the release position or vice-versa. The invention also concerns an aircraft wheel brake equipped with such a safety locking device.
