Is that a Lip damper? I have those on my 172 Cup. I feel my car doesn't handle as it should because of them (AND tired front dampers). Anyway, seeing your photo led me to do some research.
Looks like QH Lip are part of the Klarius Group and manufacture dampers for OE applications. The part number shown on yours (179604) comes up as the rear damper for, I guess, any model of Clio! Just type in the part number in ebay and you will see a Car Parts retailer selling the same part for all the Clio models. Oh, and they cost £23.85.
