Hi,
I am trying to retension the spring of the sunroof blind.
I have removed the headliner and detached the rear part of the blind.
I turn anticlockwise the spring (using a flat tool as a screwdriver) but when
I try to mount it back to its place (using my fingers or pliers to keep it tensioned) I always loose grip and the spring unwinds.
Any suggestions about the correct procedure to follow?
 
This is how to prevent the spring of loosing its tension again:

I have added the nut to act as a spacer and prohibit the blind moving too far to this side.
If this happens then the spring lock which is located to the opposite side, is released and the blind looses its tension.

And here is my unsuccessful attempt to wind the spring :(

Problem solved!
There are two slots at the end of blind.

When the slots are aligned a pin can be inserted to keep the spring from unwinding.

The pin must go through the hole and when the blind is secured the pin is removed. It is preferable that the pin is I-shaped instead of L-shape (like the one I used)
