A light switch used to operate a light where this connector is. The former homeowner must have taken the bulb or the fixture before I moved in and I had just assumed that it was a generic bulb during inspection.
It looks like there's two receptacles for prongs that connect directly to two wires separated from a single cable? There's room for maybe (guesstimating) a inch diameter pipe to slot onto it and a free floating plastic nut that would hold it in place
