Ford Ranger Dooverlacky mystery

I have a Ranger 2019 Double PU XLT according to my paperwork and am wondering if anyone has come across the mystery metal strap as per photo of the rear driver side chassis?
No sign of one on left side. Don’t think it is a wigwam for a goose’s bridle, I seem to have a few of those around the place.
My mechanical workshop manager who owns the model before mine suggested it is a prank by someone, and the few other Ranger owners I know haven’t seen one like this.

I purchased the vehicle as a demo four years ago and only noticed the strap earlier this year, but I am not overly observant, especially with motor vehicles. I haven’t been back to the dealer since I found them difficult to deal with in the first few months, so reluctant to discuss it with them unless I have to and really I am just being curious.

I checked a few Rangers skulking around the local shopping car park without noticing one alike. I will probably be challenged by someone if I keep that up.

The metal strap is quite heavy metal – almost rigid but won’t slip out when pulled with a pair of pliers, so suspect it must have been built in for a purpose and who better to ask than EO?
