- not sure if it helps Hiwex but when I had a hood cover made up for my Aero 8 by Allon Whites, they fitted a similar strap (only 1 fitted.)
It is designed to secure the potentially 'flappy' centre bit of the cover when 'pressing on' !
They fitted the 'male' part of the press stud to the rear bulkhead with a S/S screw.
I'm guessing that , as you bought your cover, which was destined for another car , the other part of the press stud is (obviously) not fitted.
Relatively easy to buy a suitable press stud kit and ,again easy enough to see where it needs to be placed.
A note of caution - make sure you know what is behind the bulkhead before running riot with the drill bit.....
HTH, James
