I just got some of these too, fairly easy to trim down with a stanley knife and fit fairly well.
BUT!
-They are pretty weak! They seem like they need more power. I was expecting something like the ones on the 2007-on Mazda 2. They are awesome washers. But I don't think they'd be suitable for the Clio because they're not mounted on the bonnet on the Mazda, they're mounted on the scuttle panel so the clips that hold them on are likely much deeper.
-They do aim high when not moving fast enough for the headwind to blow the water down. I'll get a picture later of the amount of water on my roof.
EDIT:
These Mazda/Ford ones are worth a try. I'm going to try and get some, they are far superior nozzles. Here's a link:

Ford Part Number: YL8Z-17603-AA
Mazda Part Number EC01-67-50YA
I'll post the results when I get some.
EDIT 2: These parts are for North American cars, the Ford Escape/Mazda Tribute so the PNs are unlikely to work in your local dealers. I'll update when I find out where to get these, they look like they'd be a good fit.
