Anyone use these little OPTECH strap doohickies?

I got them this week and inserted them through my split rings and now I can clip on my Optech strap using these clips.  This is a nice arrangement since at times I want the strap and at time I don't, so now I don't have to go through all the hassles of removing the traditional strap fittings.

Just thought I'd share something that's new and useful to me.
