Clutch Pedal problem

Hi All
I hope you can help me here without much expense involved. Today when i compressed and released the clutch pedal the pedal sprung forward towards me and I was unable to change gear. The pedal in a very high position. Upon further investigation I noticed that a rod connected to the side of the pedal had come loose from the body of the vehicle. I think it is linked to a major cyclinder on the engine side. I tried to reinsert the rod but it will not go home fully and will not stay in place and just jumps back out. Any suggestions as to how this can be fixed will be greatly appreciated.
thanks in advance
Richard

i think it has something to do with the clutch hydraulics, could be wrong but some1 will be along to put me right soon
