Fastening rivets for battery tray

[leef44]

In the drainage tray above the battery, there are fastening clips which are push-in rivets to hold the tray in place. There are three of them. I'm missing one. I've been trying to find out which types they are, trying to order them on ebay.

For example on
http://stores.ebay.co.uk/227s-Parts/Plastic-Fasteners-and-Clips-/_i.html?_fsub=1796417013

Has anyone gone through this process before so they know which one it is?

I'll have to get the car out to get pictures to check it out, but in the meantime if someone already knows...

Simply get them from the dealers. They will be cheap.
