Help identify something

[essex-ep]

Having a little trouble identifying this while putting my car back together.

The thing circled in the picture, can anyone tell me what it is and what it's for please?

Note, the picture is not the exact car but thats the thing i'm after.

Thanks, I don't suppose anyone would mind taking a picture of how theirs is connected so I can have something to work off. It's a pain having no workshop manual available for these cars.
