Abstract: A safety locking device for electromechanical equipment provided with a rotating shaft, particularly an aircraft wheel brake with a safety locking device. The device comprises a first friction element connected rotationally to the shaft, and a second friction element immobile rotationally and extending opposite the first friction element. One of the two friction elements is able to move in translation, under the action of a controllable actuator, between a locking position and a release position. 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 selector is maintained in any one of its angular positions by a resilient member, while the actuator provides 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.
