Outdoor table needs bracing

I have an outdoor table with poorly secured legs. Only 2 screws attach each leg at the top, and they are now at a point where they feel like they'll fall off if not secured better. I'd like to attach some bracing to support it better, matching the existing legs (aluminium). I have attached a photo of the table and of what I would like (but can't find in NZ). The table is --- and legs are 90x90.
