Alright mate, if its a Mk1 Clio, I had to do this three times in the past. Its an absolute bitch to do the first time, as ye will now know lol.
Its fiddly to fook, and quite hard to get it on the pedal.
Iirc (i havent done it since last year) you have to release the tension on the cable from the clutch by releasing the last catch on the bell housing, then you have to push the pedal catch upwards as far as it can go, then you need to pull the cable over that.
Theres so little space, its a right bitch to do, but it will go on eventually.
The thing to remeber is its self-adjusting, so you just have to get it on with patience and difficulty, and once its all connected it will set itself after a few depresses.
Good luck fella
