I ran into some fun last thursday, with a mild FTP on the M40 coming home from work

Pottering along, when *dink*, go pedal drops to the floor. Once on the hard shoulder, I fished around, expecting the clip to have come off the pedal, but no

Once the instant dread of 'well, there's nothing I can do about this' subsided, I called the big yellow taxi, who came surprisingly quick (the chap said they were quiet), and he started pondering what to do. His eyes lit up, however, when I opened the boot and handed him the new cable I'd bought 2 weeks earlier, with the intention of getting round to it (there was a white 1.9td zx hatch being broken very near me, so I had some bits off it)
However, it doesn't fit properly, but is doing the job for now. My main concern however is the white clip that goes onto the pedal. On the new cable, one of the retaining tangs is broken, and I don't want it to pop off again. However, I cannot find the clip on it's own...
My plan is, I have heard (on some other citroen type forum, and here I think) that bike gear cable comes in long lengths, perfick for chopping down to size, but I want a new, non broken white clip. My google-fu has let me down so far, does anyone know the official name, part number or a link to get one from? Or does anyone have a stash of them they would be willing to sell to me?
The only possible stumbling block I may come across is finding a length of bike gear cable with the right sized fitted end to fit onto the white clip, but I may brave town with the old clip in my pocket, pop along to the bike shop and see if they have any there that I can physically try to see if it fits, then just buy that! Can feed the new inner into the existing outer, and route it properly, at the moment the cable just sort of lays across the top of the intercooler...
How can an accelerator cable, off an identical L red 1.9td hatch, not fit mine? Going by how the original one was routed when I first got the car, it's far too short, stopping about level with the fuel filter...
