If you look at the Annex, (DR 121 Annex A) no metal clips are allowed on the pictured bridles. As a matter of fact, the Pres Teq FaySport is specifically disallowed with the comment, “Metal snaps and connections on bridle not permitted”.
I can’t really see the crownpiece, but it looks like it is separated over the poll and connected with a strap. There are maybe a couple of bridles (Elite Precision and Elite Anatomic for example) with crownpieces like that and they are not permitted for USEF dressage.I
There are quite a few listed bridle so you can get an idea of what USEF doesn’t like.
