Abstract
A socket-type terminal has an annular groove which is formed in a step portion between a base portion of a terminal connecting portion and a neck portion. A distal end of a lance head of a retaining lance for preventing withdrawal of the terminal is so formed as to fit in the groove. With this construction, when the terminal is pulled in a longitudinal direction, the whole of the retaining lance is displaced in a direction of the axis of the terminal. Therefore, the terminal is firmly retained in a housing without damaging the retaining lance.

A connector, comprising:
- a connector housing;
- a terminal insertion hole formed in said connector housing;
- a retaining member disposed in said terminal insertion hole;
- a terminal including a wire connecting portion for clamping a wire thereto and a terminal connecting portion for mating with another terminal, said terminal being received into said terminal insertion hole;
- a neck portion formed between said wire connecting portion and said terminal connecting portion;
- a step portion defined by a wall traversing the difference in diameter between said terminal connecting portion and said neck portion;
- a cavity formed along said wall;
- and
- an extruding portion formed at a distal end of said retaining member and shaped so as to closely fit into said cavity,
- wherein said extruding portion retains said terminal inside said insertion hole, and wherein when a pulling force in a withdrawing direction is exerted on said terminal, said extruding portion enters said cavity to be locked therewith.
