Is a spring clip like a lobster claw, snap hook (home depot part number 7003s-6), or belt hook? EDIT: I gave up looking for it and just decided to replace it. Was a Fenix E01 clipped to a LM Squirt PS4. Is a Fenix E05 clipped to a LM Micra with an ID tag on the ring. The ID tag has my phone number on it in case the person who finds it is honest. I'm only out an extra $3 if they're not. I may dummy cord it to my belt as an extra precaution. The jury is still out on that.
