Headlight rings - 1963 Valiant - help pls!

OK, thanks for all the tips from everyone in my previous threads on the headlight rings (bezels) for my '63 Valiant Signet.

My question this time is this:
Should there be some type of clip behind the ring?
I have seen some references to the headlight ring "clip", but I've no idea what it looks like.
I just saw a pair of headlight rings on Ebay for '63,'64 and '65 Valiant and the seller says that "they don't have the clips with them", so there's another reference to these mysterious (to me) clips.

Anyone have any idea what I'm on about please?
If so any idea where to get them from please?
Regards
Gary
