I believe you are right. And to keep the connections from un-screwing themselves on both ends.those U shaped clips hold the brake lines to the frame - IIRC
I found clips, only too large.
This makes sense, I think.
The brake hoses that were on there had no form lock. An accident waiting to happen, if you ask me.
This looks pretty good, I think. I guess the hoses were the correct length after all. Now I only need the clips.
