spring sash secondary glazing? Please help! Please!

[hellopaul]

I am trying to repair some modern(-ish) secondary glazed sash windows. Currently they just drop straight down as soon as the catch is released. I have removed one of the windows to reveal a twisted kebab-skewer-like greased rod (each side) which is supposed to slide up and down in an aluminium tube with a cyan-coloured plastic round bit on the end. The twisted rod has come out of this tube and it seems impossible to get it back in. Any suggestions? I have tried twisting it, forcing it, gently 'easing' it...everything!

Failing this, does ayone know where I can buy (cheaply, I hope!) replacement tube/rod/spiral spring units? Other than this, the windows are fine.

Many thanks in advance for any help anyone can give!!!

Are these what you require HERE

There are some pdf data sheets listed, but on the system here at work we cannot access pdf since IT upgraded or system so don't know what info they contain.
