You can really tell Honda missed their target demographic when you see posts like this...
I got my carbiners at Home Depot for < $1 ea (they've got 'em in buckets near each register). They come in many colors and work perfectly.
I actually purchased mine (gold) because it made hanging the folded seat easier as the stock seat-strap is just short enough that it's a pain to use with any regularity. Hooking seat-carabiner to the handle carabiner, which adds about 3" length, is now a snap. Now I use them for both the seat and for hanging clothes.
Buying the carbiners, vice the Honda add-ons, saves you a few bucks and, as drmabq states, gives you many color options.
