These plastic arms sit on the top of the servo to secure the wing. When the airbrake is activated, the servo arm moves to the side, releasing the wing.
In the case of a crash or a heavy landing, we want the servo arm to break before the servo itself. This bag of 5 spares will keep you going. A small philips head screwdriver is all that's needed to change servo arms.
