My wife has problems being comfortable with her seatbelt crossing too high up. She’s only short so raising her captain’s passenger seat isn’t the solution. We tried all sorts of things, large bag closure clips to clamp the straps together, even a large bull clip. Nowt seemed to work.
I bought these on recommendation supposed to fit a Ford Mustang and they look very promising.

They are substantial, very solid and fit well on the Crafter headrest supports despite being for another vehicle, and seem to do the job, holding the belt to the top corner edge of the seat regardless of the seat’s position.
Won’t really know if it solves the problem until we go on a long drive.
I’ll report back.
