ABSTRACT:
A safety device is described for use with a known safety chain. The safety device is a strip of foam-like plastic configured to fit in an elongate slot of the safety chain to prevent movement of the sliding member along the slot to thus prevent surreptitious entry. A display card includes a drawing of an actual safety chain and includes an actual slot which receives a safety device to thereby illustrate the use of the safety device in the actual safety chain.
