The second PS3 in my sig came with a snapped blu ray ribbon clip, the side mounting lugs were snapped off but as a whole it was intact.
Its hard to explain but I was able to hold the clip in place as if it was open then slide the ribbon cable in and lever the clip to close it, then I had to sort of rub the clip left and right to get it to stay down or else it tended to spring up.
I would make a video to show you how but its in there solid and working and dont want to disturb it
