I believe it mounts with and behind the retract-er assembly. The round loop portion is where the bolt passes through using the same bolt as the retract-er. They simply guide the belt into the retract-er so it doesn't get twisted as it winds back up.
Thanks for the response....after looking at it for a few minutes that is what I thought but wasn't 100% sure.
