How do you fix the black red spring loaded clips that hold in speaker wires

yes thats what i need to know, how do you put the spring back in the speaker terminal? as the spring has come out on one of my clips on my sony fh 909, some pics would be great lads, im dreading this as im partially blind, but im not taking her back to my teck as he takes flipping months, he has had my m90 for like 4 months now..

please help guys

 

Usually I insert the spring first and then slipped the finger button back in on top of it

 

Cheers Floyd, i couldn't do it and lost the bits lol but have found another lever that works and holds tight without the spring, thanks my man
