Anyone who has ever been to the emergency room knows this imaginative tool. It is used to clamp swabs or vessels in order to treat wounds. And you can use them on your bike in exactly the same way: to clamp fuel or oil hoses. Apply it, squeeze it, and you're done. Loosen by slightly shifting the eyelets sideways. Also suitable as a third hand for nasty work, for insertig screws into deeper holes, etc.
