FIELD: construction.

SUBSTANCE: device comprises of a housing 1 with an upper lid 2 and a bottom lid 3 and a cable length 4 with a passive end 4.1 and a free end 4.2, provided with a cap 5 having a neck 5.1, which is passed through the inlet 6 and outlet 7 holes of the housing 1 and a passageway 8 located between them to form a loop. Then the cable cap is fixed therein by a locking mechanism 9 spring-loaded by a locking spring 9.1. The cable cap fixation mechanism with the device closed is designed as a spring lock 11 mounted in an independent opening 12 of the bottom lid 3 which interacts with the neck 5.1 of the cable cap 5 after pushing it through the independent opening 12 when a backloop is formed. According to the invention, the spring lock 11 is designed as a shaped metal plate which, at one end, has a spring holder 11.2 with notches 11.3 for mounting it into the interturn space of the locking spring 9.1 and, at the other end, a hook 11.4 of the neck 5.1 of the cable cap, partially covering the independent opening 12 and placed in a slot 3.1 for the hook made in the bottom lid 3, which crosses the independent opening 12. The cable cap 5 of the free end 4.2 of the cable length after closing the LSD is fed into the independent opening 12 and, when it is pushed further, the hook sinks behind the neck 5.1 of the cap.

EFFECT: invention allows controlling unauthorized opening and improving the overall level of LSD protection from it.
