They;d be reasonably effective as armour, depending on how you put them together. They wouldn't stop a bullet, no way in hell, but they'd stop some blunt force and slashing trauma. Also, in order to wear them properly you'd have a fairly decent set of leather underneath, or thick padding, just like normal chain which would increase the blunt force or slashing resistance. but piercing wouldn't work so much, as they'd part when the tip of the blade got near them.

There is actually a fellow in America who has made chain armour out of pull tabs.

The bonuses of wearing chain or scale made of pull tabs and bottle tops is that it's be super light, so you could technically double-lay or triple-lay them easily, which increase their protective function by a bit. Not the best armour, but in a futuristic world where you can't get standard armour it'd be good.

Also, here in Australia pull rings are made from titanium. They haven't been made from carbon steel since the mid-eighties. Some organisations recycle them into spokes for wheelchairs once they're pulled off the can.
