🔎 UNIDENTIFIED Coupler or anchor of some kind?

It's made of some sort of non-ferrous white metal. The expandable band around the center is steel and the ends lock in place to the center pieces. The ends are threaded and if you push them toward each other, it will expand the outside diameter of the center section. Anyone recognize it?

I've seen several types of expanders but none like that..

It's not lead, but, going by 50bmg's link, it's probably a masonry anchor. I've used lots of them over the years, but, never one like this one. I guess it would be for an application that needed an anchor on both sides of a wall? Otherwise, why would you need a threaded end on both sides. All the ones I've used were ones that went into a blind hole and expanded as you turned the nut or bolt. I can't figure out how it would operate with a bolt on both sides. The ends need to squeeze together to expand. Maybe that's why this one was lost or thrown away. I may have been assembled with two threaded ends instead of one. If one end had a slightly bigger hole and no threads, you could use a bolt or stud/nut to pull the ends together.

The video included with that link confirms how it needs to work. this one must be a factory screw-up.

I call them lead anchors all the time at work because we replaced the actual lead ones with them. they are actually made out of a zinc alloy
they do go into a blind hole and only 1 side is threaded. the 2 wedge shaped pieces pull together when tightened to expand the anchor in the hole.
