A two-piece rectal insert containing a coolant fluid. The rectal insert includes a one-piece tube for holding the fluid and a one-piece cap which seals against the tube. The tube and the cap have complementary sealing structures to prevent the coolant fluid from leaking from the insert. The cap has a ring to which a string is tied. The string is pulled to remove the insert from the rectum. The cap and a wing portion of the tube provide a stop to prevent the insert from going too far into the rectum.
