Yes, I was confused with your terminology of "lockring." A lockring is generally used to describe a separate piece that holds a fixed cog or cassette in place.
I think what you're referring to are just called the notches of the freewheel itself. When the freewheel came off it came off in one piece, correct? You didn't get the freewheel and some other thing?
