Regards the post above: A quick Google of the part number told me that the clip is in fact used to retain the pollen filter cover. Courtesy of youtube, the clip is now in it's rightful place, and I now know how to fit a new filter - 2 minute job!

Incidentally, the last time the padding fell, I found this in the footwell. I assume it might be some kind of clip or fixing though I might be wrong...

I have the same issue with my 2013 Fabia Monte Carlo. Sometimes it'll go in and stay put for months, even a couple of years. This time however, it just wont stay put. I might try with some kind of adhesive tape, otherwise I'll put it in the boot!
