9 is engaged with the electrical contact portion C 1 of the shoulder portion 28 to prevent the escape after the female terminal C by (1 Tsugigakaritome terminal). Next, the terminal locking member B is slid in the direction of the arrow Q. That is, when the terminal locking tool B is pushed up in the surface contact state, the engagement between the locking groove 9 and the locking ridge 18 is released, and the terminal locking tool B moves upward.

て後退して、本係止状態はそのまま維持される。In the final locking state, even if a tensile force acts on the female terminal C via the electric wire W, the terminal locking member B is moved to the rear end of the female terminal C (the insulator holding piece 27 in the illustrated example). Functioning as a stopper against the primary lock, it is possible to reliably prevent the slippage after that in conjunction with the primary locking. Terminal lock B
When the sliding transition from the temporary locking state to the final locking state is performed, if some of the female terminals C are slightly incompletely inserted,
During the sliding, the tapered push-in engagement surface 7a of the opening 7 engages with the insulator holding piece 27 to push the male terminal C forward of the terminal accommodating chamber 1, thereby eliminating incomplete insertion. Further, in FIG. 6B, even if a turning force as shown by an arrow R is applied to the terminal locking member B by, for example, the pulling force of the electric wire W, the rotation preventing piece 15 is moved to the guide tongue as described above. Piece 2
Since the lock is engaged, there is no fear that the final lock is released. Further, in the fully inserted state of the female terminal C, the rear end 27a of the insulator sandwiching piece 27 is moved to the rear surface A 0 of the housing A as shown in FIGS. When the terminal locking member B projects slightly longer than the length = Δl, the terminal locking member B is retracted against the elasticity of the front-rear direction flexible arm 8b, and the final locking state is maintained.
