There is no equivalent for the Holy Trinity in Satanism/demonology. Some forms of Satanism may occasionally have a rough match, but in general (and in most organized variations), there is Satan and Satan alone.
The general reasoning behind that is the tri-partite "God" of the Christians is a single being, split in power and presence. Lucifer/Satan is the demonic counterpart, and is rather more unified in His power. Thus, the "good" team has some confusing 3-in-1 deal, while the "bad guys" have a pretty clear-cut who's-boss setup.
There has been a lot of discussion as to the meaning behind the trinity symbol, a.k.a. the "triquetra". Feel free to search for it on Wikipedia to read more about it. People get so worked up over what a symbol has been used for. At the end of the day, what matters is what the symbol genuinely means to you.
