Sealing bolt for sealing a container lid to a container body, said sealing bolt comprising:
- a seal head mounted to said container lid;
- a seal stud mounted to said container body;
- a pin configured to pass through the seal head and the seal stud, said pin comprising a header plate at one end coupled to said seal head, and an opposed end attached to a clamping means secured on the seal stud, so that the pin is configured to connect said seal head to said seal stud;
- and
- a cable arranged through a transverse passage in said pin,
- wherein said cable is a fiber optic, and
- wherein said seal head comprises lateral passages aligned with said transverse passage of said pin, arranged so as to pass said cable through said lateral passages and said transverse passage;
- wherein, if the seal head is pulled away from the seal stud, said pin is configured to rupture at a point adjacent the header plate, allowing said seal head to move relative to said pin and away from said seal stud, and misaligning said lateral passages and said transverse passage, allowing the rupture of said cable and providing indication of tampering.
