I think that they are click-in clips, and assuming the design is the same, it should just be a matter of unclipping the 3 clips, removing the broken assembly, and then insert the new one. You might as well remove the broken one first, before ordering, to verify that it can be done.
If not, get a new helmet. It might be a good idea to replace the old one anyway. They have a finite shelf life.
