What you call a ring that cover the 2 out of 3 parts of your index finger? - index of / !!!!!14yr!!.jpg

I see people in movies and other things are a kind of ring for the 2 sides of the class of 3 parts. The ring does not restrict a mechanism in the middle to the movement of the fingers. Does anybody know what are known as King of the Ring? and where can I get one? Thanks
