A connector including a terminal fitting having a wire connecting portion crimped to an end of a wire and configured to be inserted into a terminal accommodating chamber of a housing. A sleeve is mounted on a rear part of the terminal fitting and retains the terminal fitting by engaged the terminal fitting and a wall surface of the terminal accommodating chamber. A heat shrinkable tube is fitted on an outer periphery of the wire connecting portion while being accommodated in the sleeve and held in close contact with an outer periphery of the terminal fitting by being thermally shrunk. The sleeve includes a lift-up portion for holding the heat shrinkable tube in a fitted state so that a clearance is secured between the heat shrinkable tube and an upper surface of the wire connecting portion by lifting up the heat shrinkable tube before thermal shrinkage in a radial direction.
