Rear brake caliper pad spring thing

[TigerT]

I took the rear brake caliper apart as the pistons were stuck and binding. The spring bit fell out as I was removing calipers and I am not sure where it is meant to go. I have a Haynes manual and the photos are a bit ropey so not a lot of help!
Anyone have a pic of how the spring fits in? It's an 03 955i with Nissin caliper.

Thanks all
