FIELD: mechanics. ^ SUBSTANCE: flexible locking-sealing device includes housing 1 with pass channel 2 for arrangement of a piece of rope 3 the passive end 4 of which is rigidly attached to housing 1. It includes at least one spring-loaded locking member 5 arranged in housing with possibility of fixing the piece of rope 3 at movement of its free end 6 through inlet hole 7 towards outlet hole 8. It includes protection device preventing unauthorised access inside the housing, which is located above outlet hole 8, fixed against being offset in transverse direction relative to its axis and including process hole 9. Protection device is made in the form of metal plate 10. Process hole 9 is provided with flanging 11 along its contour with the diametre equal at least to diametre of the rope piece. Depending on the housing shape, metal plate can be rectangular, round, etc. At that, metal plate 10 can be fixed in the housing together with cover 12 having outlet hole 8. Besides metal plate 10 can be separated mainly with through cuts 13 into many circular sectors - lobes 14, and there are holes 15 along their perimetre. ^ EFFECT: increasing the protection degree of locking-sealing device against unauthorised opening. ^ 2 cl, 3 dwg |
