Ring Gag 

A 1-3" diameter ring, usually wrapped in leather, with 2 straps attached to each side that wrap around the head to hold it in place in the mouth. The main purpose is to hold the mouth open for insertion or whatever else the top can think of. Always leads to excessive amounts of drooling and messes up your speech really bad.
