there is a circular spring pin than fixes it to the rod. go to the breakers and get a pair off(then always got a spare:cheesy: ), but have a look at removing yours first so you do not break the replacement, and know what tools you need to remove as cannot remember how easy /hard it is. might be a hammer/ nail and pair of pliers.
when new one fixed always remember to press seat towards back before pulling lever, as that is the main cause of breakage as the pressure involved to release the spring and hook is considerable, but drastically reduced just by pressing the seat back.
It's like putting our 900's in forward gear before selecting reverse, it helps
