Sounds like the end of the cable has broken off, if that's the case and it's not the pedal end that holds the cable.
I would replace the clutch cable.
I picked up a spare cable from the junk yard in Vegas, we have what you call (pick a parts)
where you do it yourself removals, it costs me 5 bucks each. ( 60 bucks at the dealer)
I snagged a spare throttle cable also.
Just in case either broke on the trail.

I can't take the cold, so I think I would have broke too.
