A door configured to be selectively closed and fixed on a frame,

• said door comprising a closing system equipped with actuator means, at least one anchoring element and a mechanical transmission, said actuator means being configured to move said at least one anchoring element between a first operative condition in which the at least one anchoring element does not cooperate with said frame, leaving said door free to move with respect to the frame, and a second operative condition in which the at least one anchoring element cooperates with said frame to fix said door to the the frame,
• said door comprising a safety system for said at least one anchoring element, said safety system comprising a source of light radiations and a receptor of said radiations, said source being integral with one of said door and said anchoring element, said receptor being integral with said one of said door and said anchoring element, said receptor being optically connected to a signalling means, and said signalling means signalling the positioning of said anchoring element in said second operating condition when said receiver receives said light radiation from said source,
• wherein said safety system comprises a shielding element, said shielding element being integral with the other of said door and said anchoring element, said shielding element preventing a passage of light radiation between said source and said receptor when said anchoring element is in said first operating condition and allowing the passage of light radiation when said anchoring element is in said second operating condition, wherein said shielding element comprises a flange integral with said other of said door and said anchoring element, and said flange-being provided with a through hole-configured to enable the unaltered passage of said light radiation.
