I feel like a idiot
because I didn't look on the hose clamp itself as the brand name and size is engraved on it. The name and size on the clamp is Oetiker and 15.3. With this I did a google search and the actual name of this is called a ear clamp and you don't need a special tool to install them. The tool that I bought is a end cutting pliers. Tomorrow I will stop at the hardware store to see if they have this ear clamp in stock as I need to buy a couple more. Here is a couple of links for the
ear clamps and
end cutting pliers for reference.
