The hasp is designed to be used with a round cylinder lock of the type disclosed in U.S. Pat. No. 3,769,821 and sold by the American Lock Company. The hasp of the present invention is comprised of a steel reinforced plate, the steel reinforced plate has a truncated circular indentation on a front side thereof for encapsulating an outer diameter of the round cylinder lock. The truncated circular indentation has a hasp hole, a locking pin extends from the round cylinder lock and is receivable in the hasp hole. The hasp hole is sized slightly larger than the outer circumference of the locking pin, the locking pin is fixed to the round cylinder lock and extends axially outwardly thereof. A plate lug is supported on the steel reinforced plate and projects axially outwardly of the truncated circular indentation for telescoping engagement internally of the round cylinder lock, the plate lug has a plate lug hole extending at right angles to the plate lug. A sliding tubular lock shaft is located within the round cylinder lock, the plate lug is extendible into the round cylinder lock for receipt of the sliding tubular lock shaft within the plate lug hole, thereby enabling the plate lug and the hasp to be secured in locked assembly with the round cylinder lock.
