The PVC is 1/2 inch - I use a 3/8 pipe nipple and a 3/8 brass cap. I drill and tap the brass cap for 1/4-20 and use a 1/4-20 Phillips head machine screw and thread it into the cap with a lock washer and then thread the cap onto the nipple. The nipple is a tight fit in the 1/2 PVC (might have to do a little Dremel work to get the nipple to thread in). I then use a stainless hose clamp to hold the nipple and a stainless D ring in place (for a neckstrap connection).

Thanks very much for the information- you are definitely handy and inventive at these sorts of things :)
