Found this in the garden, looks like something used to key 2 bricks
together, but why is there a twist in the middle?

Its a vertical twist tie used to tie cavity and external walls.

They're laid on a slight slope. The twist is so that any water
or built up moisture or condensation drips off the twist in the
middle of the tie rather than running down to the end and soaking the
cavity wall.
