you have to buy the whole handle : ( unless you can find the part on eBay! the locking ring wasn't pulled back far enough and the small part then falls out.
Just buy a new cap but make sure the lock mechanism on the passenger side is locked in place properly before fitting - poke a screw driver through the grommet hole in the side of the door to push her lock ring mentioned. The aftermarket handles I brought had covers that fit ok but I did have to trim a smidge off a lip to make sure they clipped in securely. My genuine Renault passenger side lock cover fitted a bit better. That said, my aftermarket cap has been on a while now and doesn't look like it is going anywhere.
I got a new genuine one off eBay for bout £8 god knows how the last one came off its hard to put on it fits so tight haha
