It sits behind the disc, but is slightly larger. So you can push the edges with your finger and it flexes enough for it to drop out

If this happens again, what bit is the splashgaurd? Does anyone have a pic of one please? 

....Splash guards, also known as stone guards, are not something which folks feel a strong desire to photograph for some reason  

It's the thin metal shaped disc which is mounted parallel to and near the inside face of the disc brake. They are usually painted black.

I don't have any fitted on my rear S3 brakes.

As mentioned, it's the large metal plate behind the discs.

Just how important are these metal disc stone guards? Especially when they trap stones and probably do more potential damage than a quick strike.
