Abstract
Abstract A security shield for protection of the shackle of a padlock makes use of a sheet of metal of relatively heavy gage which has one portion bent to a position where it overlies one side of the shackle when the shackle is in locked position on the body of the padlock making it difficult for an unauthorized person with an appropriate rod cutter or chisel to cut through the shackle and release the padlock. The shield is attached to the padlock itself, either permanently or temporarily, by use of a second portion of the sheet of metal bent to a suitable position where it is attached to and carried by the body of the padlock.
