Elise Parts s1 shower cap

[Haves1979]

Hi,

Just wondering if anyone has an idea of how the Elise Parts S1 shower cap attaches at the rear with the roof fitted?

The front is straight forward with plastic buckles, however the rear has two elastic loops but for the life of me I can't see how it attaches to the car...

Any pointers appreciated, cheers!

If the shower cap has loops at the back they will go around the 'tails' on the roof.
