ABSTRACT:
A padlock presents a straight shackle axially slidable in seats provided in two wings obtained in the padlock body, so as to be capable of closing a U-shaped recess defined by the said wings. The shackle is locked in its closure position by a latch pin the movement of which is controlled by the rotation of a cylinder of a cylinder lock of known type, housed in the padlock body. An armour jacket made of steel is vested onto the side surface of the padlock body, thus conferring to the padlock a protection against attempts of breaking open. The said armour jacket also serves for closing the bores for the pin tumblers and the bore for housing the latch pin, and of any other bore made in the side surface of the padlock body for housing the components of the padlock mechanism.
