Abstract: A guard for enclosing the shackle of a padlock secured to a hasp staple comprises a substantially U-shaped housing comprising a front wall and spaced apart side walls connected to the front wall; and a rod connecting the side walls and spaced apart from the front wall. The rod divides the housing into upper and lower portions. The front and side walls and the rod are configured to permit the padlock to be received within the housing such that the body of the padlock is disposed below the rod and the shackle of the padlock between the rod and the front wall. The rod is positionable between the body of the padlock such that the housing is held captive to the padlock. The upper and lower portions of the housing are adapted to enclose the shackle of the padlock at least in one position of the rod between the staple hasp and the padlock body.
