I'm not sure why you'd need this. Perhaps if your Wiimote had stopped being a gaming accessory and started being a security blanket? In case you were in the middle of a game and needed to ensure you stood no risk of dropping the controller? Whichever of these applies to you, I'd recommend making your own version using a simple elastic band round your hand and remote.

Though not a product I would personally use I can see the use for others like the girl in this link.
