Agreed. Saddle shields were riveted. Though the piece does resemble a coupler for coat straps or saddlebags, after looking through all my resources, it seems that it is a newer piece. Specifically looking at the tabs underneath that are bent over to complete the connection making it a double-sided fastener. It looks like it would hold up well, but not for extended use or for a combat role.
I know this is far off from what you have there
@kcox418 but it is the closest I can find to a double-sided strap connector on a saddle.
As
@Rhea Cole points out, it could have come from anything.
Please correct me if I am wrong.
