ABSTRACT:
In a certain form of key-operated padlock of generally curved contour with a flat bottom there is accessible from the bottom of the padlock body a generally rectangular crevice outlining the cavity in the body block which flushly receives the retainer block and cylinder. In the present invention the padlock body and the enclosed retainer block have mating and cooperating eccentrically shaped ribs and grooves which are effective in preventing unauthorized attempts at a tool insertion in the crevice surrounding the exposed end portion of the block sufficient to separate portions of the block and the enclosing padlock body, or to break out wall portions of the latter. Additionally, unauthorized disengagement of the retainer block from the padlock body is prevented by a pair of hardened pins which extend from the padlock body into the retainer block and are rotatably mounted in the latter.
