The collar fits the tube above the chuck on the bottom of the quill.
To remove your broken collar, remove the chuck and undo the slide with the depth gauge. Slip the old one off and replace the new one. Insert and tighten the depth gauge, then secure the collar flush and tighten locking screw.
Now you will be able to accurately drill the same depth holes in your work piece.
