AFAIK this is what mcbrat needs
it is indeed a two-part ring which both crescents get connected and wrapped around the tailcap's groove
A lanyard gate clip is something else and can be user-replaced; although, SF's own design and heated surface treatment seems to be unique
Whenever I get a SF lanyard kit I always remove and replace it by another swivel hook (swivel gate clip, whatever the name is) which is more convenient
When I get home I will check to see if I have a spare one. Not sure if I do anymore but, I checked my office desk (random SF parts) and don't have one. I have no problem mailing it to you free if I can find it. Let ya know this evening.
