Cookshop halogen oven spiral spring location?

Where does the spiral spring fit, whilst waiting for spares forgot where it located, vid on youtube doesn't show it..

FYI if bulb is sparking element has broken, intermitant contact, via vibrations result in the sparking. Inducing sparking with a shake one way to confirm fault is the bulb..
My bulb lasted 4 yrs almost to the day, avoid knocks to lid when bulb is hot..
Supporting lid on something like a beanbag can help during repair.
