The present invention relates to the means of protection from the uncontrolled access with aid of sealing and it can be used for control of the access to the protected object, as well as for its identification. The sealing device contains destroyable layer (2) with adhesion coating (3) applied to the side intended for contacting with sealed surface (5) and adhesion coating (4) on the other side of destroyable layer with film layer (6) fixed to it. The sealing device is provided with lens (7) placed on the said film layer (6), and being so, the materials of the layers are chosen so that adhesion between destroyable layer (2) and sealed surface (5) has a bigger value than the adhesion between destroyable layer (2) and film layer (6), and the adhesion value between film layer (6) and lens (7) exceeds the adhesion value between film layer (6) and destroyable layer (2). |
