This ratcheting plastic band clamp is used to secure the lower radiator hose. The clamp has a little plastic nub that locks into a tiny receptacle at the bottom of the radiator support. It's a friction fit. If I give Moneypenny the spurs the clamp pops right out. I don't like the coolant hose banging around. I'm mulling modifications that allow me to secure the hose more reliably. Right now I'm using a handcuff zip tie.
