Those who are married, is your wedding ring a shield agasint "hitting on"? Those who are single does it work?

I was once married, not since a long time.
What I can say is that never hitted in no one else than my own partner when and while in a relationship, ring or not.
Was i "hitted" when I had a ring or by ones that knew that I was "taken"? Or single but by married ones?
Yes, sometimes, few ones.
I declined.
