Rear wiper trim on w203 estate

I've done a few searches but, not knowing what the part is called, I might not be searching in the right places!
I had my rear screen smashed this morning on my 2005 c180 estate. Apart from the glass the cover thingy which hinges over the rear wiper and washer nozzles has been smashed. I could just wrap some tape round it and ignore it but I imagine it is a reletively imexpensive part (even though it is for a MB!).
Can anyone help with a description/part number please and whether it is easy to replace (I can't look at the moment as my car is in having the glass replaced!.

Thanks in advance

Could be this, flips down over the spindle and washer jet -

A2038240449 - CAP, REAR PANEL DOOR PANE WIPER (£5.34 from MB)

 

Sounds like that could be the very thing. When I've got my car back I'll pop along to MB and get myself one.

Many thanks

Just following on from my last thread - I don't seem to have any sort of nozzle under this cover and, now I've changed it, the water just dribbles out.
Can anyone let me have the part number for the nozzle that I need please?

Many thanks

 

In case anyone follows this thread - the part number for the nozzle is 2038601747
