A seal-lock with destruction-identifying structure includes a body having an opening in communication with an interior of the body. The seal-lock further includes a bolt having a shank. The shank and the body are so configured that coupling of the shank and the body is easy but disengagement of the shank from the body after coupling of the shank and the body is difficult. The bolt includes a head on a top end of the shank. The head has a diameter larger than a diameter of the shank. A transparent protective cover is mounted around the head and the shank. The shank can include a tag or pattern formed on an outer periphery of the shank. The tag or pattern is selected from a group consisting of letters, figures, symbols, and numbers. The tag or pattern is exposed out of the body after the shank is coupled with the body. |
