ABSTRACT:
A device for securing a shackle by limiting the rotation of the cross bolt includes means, such as a jamming block, for blocking the path of rotation of the cross bolt's head, and means for holding the blocking means in its blocking position. This holding means can comprise a flange which will restrict movement of the jamming block, or a spring urging the block into its rotation blocking position. The shackle securing device can be made tamper-proof by locking it onto the eye of a cross bolt with a padlock.
