That spring clip is bent open to far right at your thumb nail in middle photo, the cross bar part should be centered over the middle of the loops.
Take some small needle nose pliers and slowly bend it clock wise till it is centered. Slide the loops over the sleeve and just lift the tab end up to clear the sleeve and slide it down till the cross bar pops I to slot.
This a common problem on the clip when over pushing tab to release cable.
