2012 Estate boot cover : Replacement side clip?

[homerjh]

Hi All, lurker here...

I have a 2012 estate and one of the clips on the boot cover that slide along the edge runners has broken off.

I have hot glued it, but it is only a matter of time before it falls off again, and it needs it to keep the cover tight.

Now i can get a new full unit from ebay for £50+ but it is a company car and i am loathed to pay this just because of a £5 (guesstimate) bit of plastic that just needs to be replaced.

Now i have googled and cannot find what i am looking for, but i am not 100% confident that i am searching using the correct terms, but i would think it is a part that would be available somewhere.

any assistance gratefully accepted.

Thanks
