It looks like it should go on top of the spring assembly which has a slot in it that roughly matches the size of the bar on the white clip, yet no matter how I try to push it in it won't seem to go. It also seems to be a frustrating case of 'nearly but not quite' so to speak.
I've tried with the clutch in the depressed position and in the released position, I just can't get access to it. It looks like I may have to take the pedal off to get enough access to clip it back in. The cars in a car park at the moment so I will take my tools tommorrow for a better look. I've got enough slack to manouver the cable, its just clipping it into the pedal bit that I can't seem to do.
