Anti-theft device of a bicycle wheel includes at least one braking unit having two pads acting on a rim of the wheel and an actuator to control at least one braking unit. The actuator includes two tie-rods pivoting on shafts and is actuated by a key acting on a key cylinder to press the pads on the rim of the wheel. Each tie-rod is driven at one end by a secondary transmitter piston interacting with a primary transmitter piston and driving a receiver piston holding the pad at its other end. The rotational movement of the key cylinder is converted into a translational movement of the primary transmitter piston by an indirect movement converter.
