Apart from two molded clips to locate the sleeve on the anchor strap, they were also melted and fastened through the plastic onto the strap. They were also likely assembled in place so the webbing was fed through and then the steel strap added inside as it doesn't really fit back through it. You can make it but often if not already cracked or broken, that's when they will. Check pic, otherwise, masking up isn't too bad! Otherwise some hot water might make it extra flexible just for a minute, remember they are only available used and more often not at all.
