The 22-year-old, who joined the Rams from Ilkeston Town in the summer of 2009, has made just seven starts for the club in all competitions and joins the Gulls looking to gain further first-team experience.
Torquay boss Paul Buckle told the club's official website: "We are very grateful to Derby manager Nigel Clough, who has been brilliant throughout the process."
"Ben is a left-midfielder and will add strength to our team. We needed to cover a gap after Ryan Gilligan's return to Northampton.
"Ben is technically very good and I am delighted to have him on board."
Pringle will go straight into the squad for the visit of Stevenage to Plainmoor on Saturday...
