[Shop-talk] Retaining ring pliers?

I'm helping a friend fix a BMW starter. The starter gear slides along  
a shaft and is stopped by a collar held in by a retaining ring. The  
ring is a round section type like these:

and it simultaneously fits in a groove in the shaft, and in a groove  
in the collar. Here's the fiche from the bike, and "Starter Single  
Parts" will open the diagram:

I'm looking for a tool(s) that would assist in compressing the ring to  
allow the collar to slide off/on it, and also expand the ring to ease  
removal from the shaft. There's already been one screwdriver-under-the- 
fingernail episode...

thanks,
jim
