chain lock
Linked metal latch
A chain lock is a security device consisting of a short chain attached to a door frame, with a sliding bolt that engages a track on the door itself.
It allows the door to open a few inches while preventing full entry—enough to see who's there or receive a package without letting someone in: She spoke to the stranger through the chain lock.
