Abstract

The invention relates to devices for preventing the unauthorized access to objects, such as sealing-locking devices, and can be used for sealing of various goods, tariff counters, containers, wagons, as well as various special packages, equipped with sealing units.The seal comprises a body (1) in the form of a cup and coaxially disposed therein a core (8), in which perpendicular to their axis are made coaxial through holes (9) for a flexible sealing element (19). The core (8) is provided with a ratchet with two identical ratchet pawls (10), interacting with the possibility of rotation in one direction with the longitudinal ribs (3) of the ratchet, made on the inner cylindrical surface of the body (1). On the core (8) are placed three spatially separated discs (12, 13). The end surface of the discs (12, 13) is provided with at least one guide groove, made in a helical line. The guide groove of the disc (12) is made with open ends, and the guide groove of the disc (13) is made with an open end and a hollow opposite end. In the body (1) is made an internal annular groove, at the edge of which is placed at least one projection (6) with the possibility of entry and displacement in the guide grooves of the discs (12, 13). On the outer end of the core (8) is fixed a detachable plate (17), provided with separable tabs (18). The third disc is made opposite to the annular groove of the body (1) for forming a tight connection.
