ABSTRACT:
Roll-down shutter with a rotating, self-locking winding shaft with coilable shutter armor made of linked interconnected shutter elements, whereby the top-most shutter element is attached to the winding shaft. In order to make an unauthorized separation of the shutters from the winding shaft practically impossible, the top-most shutter element is bound closed-shape with the winding shaft.
