In modern use the Triquetra, also known as a "trinity knot," is believed to represent the three promises of a relationship such as to love, honour, and protect. It's an ancient symbol though and appears on runestones in Northern Europe being associated with Odin and can represent the triple goddess and protection for Wiccans and other neo-pagans.
The Triquetra also appeared on Led Zepellin's Fourth Album so whatever the symbol means to you personally this design will make you cool.
