My guess would be a small loop that captured the ring that was held firmly to the scabbard. Not movable. If there were some adjustable mechanism for the strap, it would not be at the ring, as nothing of the kind shows in the pictorial below. Since a sword was an individual item, it seems like the strap would be made the "right length" and not need adjustment.
