Just go down to your local scrappy and get some off a Clio in there, or you can try Renparts or whomever. Don't get them from eBay, unless they're genuine OEM, because I made the mistake of buying one back when I had my 1.2 and it was a poor colour match so never ended up using it.
The key thing to be sure of is the handles have a little metal square that the torx screw goes through, if you take the screw all the way out you will more often than not lose the little metal square to the inside of the door, so don't take the screw too far out.
