Sliding Door retainer spring

Does anyone have a clear image of how this spring fits please:



I cant see exactly how to put it in place!!

 

Ignore - worked it out finally!!!

 

Tricky little beggar, took me a while to figure out too.

 

Its harder when you havent got a spring, just a pile of wooden clothes pegs and a pair of pliers . Didnt help on mine that somebody has smashed the corner off the casting so it didnt look right.
