One circlip inside to lock the cable to the back plate.
My after market cable had two circlips, I took one or both off and used one to lock it into the backing plate, I had to use a little muscle to get it to line up and snap the circlip into place. even then it was a little loose, not snug like OEM expanded springy thingy. Once you get it hooked to the parking brake lever and brakes adjusted, it will tighten up because the springs hold it in.
