Abstract: A security cover for a padlock securing a door lock or the like comprises a first part for mounting on the door or door frame and a second part hinged to the first part so as to be moveable into a closed position covering the lock and at least the shackle part of the padlock, to restrict burglars from cutting through the shackle with bolt cutters. The second part has a suitable eye member or device mounted on its inner face for co-operation with the door lock in its closed position so that it can be locked closed by the padlock at the same time as the door is locked. The security cover may itself form the hasp of a door lock or may be completely separate from the lock.
