ABSTRACT:
This fall-prevention device comprises a body on which, mounted so as to rotate about a shaft, there is a wheel designed to press and roll on a belay support, and means for locking the body of the fall-prevention device on the belay support, the wheel comprising at least one centrifugal engagement device that can be moved between a disengaged position and an engaged position. The locking means comprise at least one locking member mounted so as to rotate on the body about the rotation shaft of the wheel, the locking member comprising a chock arranged to be inserted between the belay support and the wheel when the engagement device is in its engaged position, so as to immobilize the fall-prevention device on the belay support.
