Ah, the things you find hiding behind nailed wood panels...

Hello Lazy Web. What is this thing?




If you squeeze it in the direction the arrows below indicate, it compresses a little bit, with the prongy-side sliding into the metal casing.


In the Dungeon, there is a panel labeled "Phone Connection: Remove Screws Only". Of course, it's nailed shut, with no screws in sight. After pulling out the nails, it turns out it's an old school screw-down connector; actually not that interesting. But down in the bottom of the box I found those two things up above.

Anybody have a guess?
