ABSTRACT:
A seal of the padlock type comprising a plastic body having a pair of spaced apertures for receiving straight ends of a wire shackle. A metal fastener is assembled in the housing, said fastener having flexible tongues for so engaging the shackle ends that they can be easily pushed into the housing but cannot thereafter be retracted. In one embodiment of the invention the body is formed of upper and lower body portions which retain the fastener therebetween. The fastener and the upper body portion have weakened portions which fracture when excessive tension is applied to the shackle.
In another embodiment of the invention the fastener has transverse score lines and the upper portion of the body has corresponding weakened portions, so that excessive tension applied to either shackle leg will cause fracture of the fastener and the body.
