Yeah so what can it be?

About two and half inches 3 inches long

I think it's a choker ring that goes on the end of a cable, rope, or chain. They are good for lifting or dragging things like logs.

Horse tack item

Ironhorse is right... horsegear. More specifically, it is a "gag swivel" from the "gag chain" on a horse's bridle. We are sure that that's the correct identification, because the parts are shown in diagrams in 1890s-&-later horseharness mail-order catalogs. See the scans below. They cannot be accurately dated, because they are still being made and sold today. See the shiny new one for sale on the internet in the photo below. However, since most Americans had stopped using horses for personal transportation by the 1940s, your find is statistically most likely to be from the late-1800s/early-1900s.

Agreed with IH and CBG.
