The utility model provides a sealing device, and belongs to the field of anti-counterfeit technologies. The sealing device comprises a shell and a lock, a cavity is formed in the shell, one end of the shell is an open end through which the inner side and the outer side of the cavity are communicated, line penetrating holes are formed in the shell, sealing lines can penetrate through the line penetrating holes, a step is formed on one side wall of the cavity, the lock can extend into the cavity, the lock comprises a body and elastic pieces used for abutting against the step, the end of the body is connected with one ends of the elastic pieces, the body and the elastic pieces are integrally formed thin metal pieces, each elastic piece inclines in the direction perpendicular to the larger side of the body, the step is arranged on the larger side wall of the cavity, and sealing line grooves are formed between the elastic pieces and the body. Because the body and the elastic pieces are the integrally formed thin metal pieces, the body and the elastic pieces can be bent by a certain angle, and in the manufacturing process, it is only required that the shape of the lock is formed and then the elastic pieces are bent; in addition, the thin metal pieces are thin, the width of the cavity does not need to be too large so that the thickness of the whole shell can be substantially reduced.
