I don't think the bike has any clips like that. I know I haven't seen any on the parts fiches. However, like mentioned above, maybe someone changed out a split pin.
In that vein, the rear brake push rod has a split pin that could have maybe been changed to that. Here it is:

I just looked through the parts fiche for the '13 and did not see a clip like that. Haven't seen one on my bike either. I'm guessing its an undocumented part for the reticulating lever arm that meters blinker fluid...
