发明名称 Tamper proof padlock hasp apparatus
摘要 A tamper proof hasp apparatus for use with a conventional padlock incorporating a U-shaped attached shackle pivotable, when unlocked, about a shackle pivot leg. The apparatus includes first and second hasps incorporating respective first and second hasp plates formed on one end with an opening for receipt laterally thereinto of the pivot leg of the shackle and formed on the opposite end with bores for receiving the closure leg of such shackle. The closure bore of the first plate is of such a diameter as to receive the closure leg of the hasp and to engage the curved portion thereof to limit the extent to which such hasp may be inserted. The respective hasps are formed with guard plates projecting laterally thereof to, when such hasps are mounted on respective parts to be locked together, restrict access to such shackle by tampering tools such as bolt cutters, hacksaws and the like.
