A female terminal portion 3 is provided with an inner peripheral engagement surface. An external cylinder 9 is provided around an outer periphery of the female terminal portion 3. In the external cylinder 9, when first opposite wall portions 10 constituting a pair are pressed, second opposite wall portions 11 constituting a pair are flexed and separated from each other. Both first opposite wall portions 10 are provided with respective pressing pawls 14. Both second opposite wall portions 11 are provided with the respective locking pawls 15. The pressing pawls 14 abut against a front side wall of the annular convex portion 6 when both first opposite wall portions 10 are pressed.
