most of you will probably already know what im going too say

4 words... white clip (and) black clip
the rod within the, what i can only explain as inside the cylindrical thing, isnt going in when pressing the clutch pedal, causing the black clip to pop off and the white clip to pop out of the metal 'jacket' that is attached to the cylindrical thingy
so currently my car is stuck at work with no clutch pedal, how can i fix this? the black clip isnt broke but it wont stay on, not even with cable ties (they snap)
any ideas greatly appreciated

cheers ta, thanks very moochos!
