The pieces used to secure them in place are called various names including straps, brackets, clips and pipe bands. They are made of the same material at the gutters they are being installed on.

The design of these pieces can vary from plain to intricate. They typically wrap around three sides of the downspout and are nailed on each side to the siding. There are some designs that wrap all the way around the downspout meeting in the back of the downspout and being secured by one screw.
