ALEXANDRIA, Va., Feb. 24 -- United States Patent no. 12,559,974, issued on Feb. 24.
"Latch tampering indicator" was invented by Timothy J. Costello (South Bend, Ind.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A device for indicating that a latch has been opened or tampered with includes a base, a head and a body having a frangible section. The body connects the base and the head. In use, the device is inserted into a latch in the closed or latched position. The device is positioned such that opening or unlatching the latch breaks or otherwise severs the frangible section, thereby separating the base from the head."
