FIELD: process engineering.SUBSTANCE: invention relates to locking devices and can be used for sealing water, gas electric power counters, etc. Proposed device comprises body including blank cavity with bore made at its top section. Side surfaces of said body include at least two thrusts. Besides, it has travel limiters arranged in said blind cavity on bore side. Note here that front and rear surfaces have two aligned bores. It incorporates locking element with side surfaces including at least two elastic teeth directed along travel of said locking element. Note here that one end of said locking element comprises cover to overlap the bore surface. Opposite end of said element is located opposite the locking element base side. Note here that said bore comprises thrusts while both ends of locking element composed by a cut-out are spring-loaded by flat compression spring. Said spring has the rod on blind cavity base side. One end of said rod extends beyond said spring while opposite end is shaped to the wedge and includes bores located in one axis with bores and having a flexible arch.EFFECT: proper locking to inhibit unauthorised seal removal.2 cl, 3 dwg |
