Yes there is a different name for them, they are also known as tandem hooks. one or more trailing behind another one. l do not know much about actually tying them on as l usually buy them for my rigs already pre tied however l have included a web site that will give you more info on how to tie them up and how to fish them with both live and plastic worms.
