Abstract
A tubular hasp for padlocks having U-shaped shackles comprising two tubular elements that attach separately to each side of a closure structure. With the closure in the closed position and the padlock shackle in the unlocked, open position, and rotated away from the closure structure the padlock will fit into the larger tubular element until stopped by the shackle coming into contact with the front wall. The padlock is moved toward the smaller tubular element and the shackle rotated through an opening provided in the front wall of the smaller tubular element until it reaches alignment with the mating hole in the padlock. The shackle is then closed, latched and locked within the padlock body. The combination of these elements provides a secure arrangement of tubular hasp and padlock with the shackle protected from the commonly used methods of forced attack.
