の目的は、端子金具に対する保持強度を高めることの可
能なコネクタを提供するところにある。Since the lance 4 is thinner than the peripheral portion so that it can be flexibly deformed, the lance 4 has a relatively low strength, and the wire W connected to the terminal fitting 2 is pulled by a terminal or the like. If a strong force is applied to the metal fitting 2 in the pulling direction, the lance 4 may be deformed or damaged, and the terminal metal fitting 2 may come off. In order to increase the holding strength of the lance 4 with respect to the terminal fitting 2, for example, the lance 4
It is conceivable that the connector housing 1 is made larger to increase the rigidity, but this leads to an increase in the size of the connector housing 1. The present invention has been made in view of the above circumstances, and an object thereof is to provide a connector capable of increasing the holding strength with respect to a terminal fitting.

ることも可能である。As described above, according to this embodiment, when the female side terminal fitting 10 is mounted, after the female side terminal fitting 10 is inserted into the non-locking position with respect to the fixed locking portion 29, the terminal straightening is performed. The female terminal fitting 10 is retained and retained by being displaced to the proper mounting position by the rubber stopper 15 or the retainer 40, which is a means, and locked by the fixed locking portion 29. When a force in the pulling direction is applied to the female-side terminal fitting 10, the force is received by the fixed locking portion 29 that does not bend and deform.
Deformation and damage are less likely to occur as compared with the conventional lance, and the holding strength for the female terminal fitting 10 can be increased. Further, since it is not necessary to provide a lance or a bending space for the lance in the cavity 23, it is possible to downsize the female connector housing 20.
