Knocked my hydraulic clutch line off the transmission

My muffler fell off and knocked my hydraulic clutch line off the transmission. I lost the black quick connect clip and clear retainer I made both because you cannot buy them any where. I got everything back together and the clutch pedal got hard and it would not go down. I tried bleeding nothing, I took off the master cylinder and I changed the o-rings. I put it back together bench bled and fill the fluid. Now it is going all the way down line, but not in slave. I made sure the line was working, still nothing. I tried pushing fluid in bleeder and it pushed back what is going on with the system?
