摘要

The lock protection is composed of three elements. A stainless steel anti-drilling excluder (2) having a fold to repel drills. An 8 mm tube (1) for rotating around the lock fixing screw (D) in case of an attempt at drilling. A stainless steel protecting cylinder (3) comprising a drilled piece (C) for reinforcing a weak resistance point and allowing passage of the screw, completed by a plug (E) against the drilling of the cylinder and protecting against forced extraction of the rotor.
