I'm after some stretchy fasteners for holding things like the doors on
a chicken coop and various other hatches closed.

Basically I want something that comprises a hook on one side and an
elastic loop or toggle on the other side with a handle of some sort to
make it easy to pull the elastic over the hook (or engage it in the
toggle).

Ideally the metalwork (if any) would be stainless steel or galvanised
but all non-metallic would be equally acceptable.

Currently I'm using Screwfix toggle latches (item 15443) but these are
really a bit small, go rusty and can't tolerate as much "wobbliness"
as I would like.

Any suggestions?
