I don't see a spring, check difference in height between diaphram spring fingers, adjust fingers if height differential exceeds specifications.
So it would seem the diaphram fingers provide the "spring".
However, as Rasmataz pointed out, the cable itself could be binding.
I would disconnect cable from clutch pedal, check clutch pedal for free movement at pivot, if OK, then replace the cable. If problem persists, you will have to adjust fingers, or replace diaphram.
