The present invention relates to closing devices used for protecting the doors of containers on railway wagons, for instance, against the intrusion of unauthorised persons. This invention may be used for increasing the seal reliability and more precisely relates to a wire seal that includes a body comprising an axial opening for the wire. A plug is attached to one end of the wire for limiting its displacement. The wire seal also includes spring-loaded balls co-operating with the wire and located in chambers with inclined walls, wherein said chambers are formed in the walls of the body and communicate with the axial opening. The body has a conical shape and comprises a cover on the side of its smaller diameter. The cover comprises a profiled opening that conforms to the shape of the wire in order to prevent rotation of the body relative to said wire. A stepped opening is formed within the body under said cover and has a ring fitted therein for interaction with the spring-loaded balls, wherein said ring is made of a material softer than that used for the balls. <IMAGE> |
