(54) Anti-theft device for manhole covers and related securing method


(57) This invention relates to an anti-theft device and method applied to hinge-based locking systems, in particular, those used in manholes. The device comprises a ring (1); a lid (2) to connect with the ring; a locking hook (3) of the lid (2) pivot that is placed onto cavities (1A and 1B) located in the ring (1); the lid (2) comprising a set of joining means with the ring. The ring (1) of the assembly can be located either secured to the ground with bituminous filler, cement or fixed with further binders and, to prevent the cover theft, the hook (3) external body is entirely covered with the pavement, so that solely with its removal/destruction will it be possible to take the lid out from the ring. The hook (3) may be placed in a stage when the ring (1) is already partially secured to the pavement. This invention is, therefore, chiefly useful to prevent the cover theft, while maintaining, on the other hand, all typical features and functionalities of the assembly.
