Use a plastic tie-wrap. Keep the chain in place, and wrap the tie-wrap around
the top of the chain (preferably through an opening) to prevent it from
falling down. Then, insert the tie-wrap through every other link in the chain
down towards the bottom.

The tie-wrap will stiffen the chain so that it can't tangle up, while still
allowing the chain to support the weight of the flapper. So the tie-wrap
should never wear out (or at least I won't be around long enough to find out
otherwise).
