Abstract
A security shield for padlocks having U-shaped shackles and used with traditional hasp, staple, and various other types of attachment devices. The shield is a tube like device into which the padlock will fit, with a tab to limit longitudinal travel, and provided with clearance openings permitting the free swing of the unlocked shackle, and engagement with the attachment devices to be made secure. The combination of these elements provides protection for the shackle, and attachment device elements from the commonly used methods of forced attack.
