Something hanging off under the van

Hi all, just noticed something hanging off under the van (2015 Sprite Major TD6).

It is an L-shaped piece of metal, maybe a bracket, and seems to be attached to the breakaway cable.  Not the best photo, I apologise.

So anyway, it seems to be hanging/swinging freely so I'm not too concerned about damaging anything if I catch it on something on the ground/road, but what is it ?  Some kind of guide for the breakaway cable perhaps ? Will need to get it fixed eventually but would be good to know what it is and that it's not desperately urgent/important.

Thanks in advance for assistance.
