Need idea for broken latch on an aqualogic control metal box

The latch broke off on my aqualogic control box so the wind can blow it open.
I tried to find a similar latch on amazon but could not.
Would love to hear some genius ideas how to keep the door shut.

Already tried
putting magnets on door and body and have them pin a plastic strip to body
Velcro but sticky faced wrong way
ordering from amazon

Looking for new ideas!

Thanks
