ない。1 and 2 show a first embodiment of a double locking connector according to the present invention. In the double locking connector of this embodiment, rib-shaped convex portions 11 are vertically projected on the tapered surface 9 of the rear surface of the housing lance 4, whereby the tapered surface 9 of the housing lance 4 is protruded. Only the protruding part of is straight. Correspondingly, the tapered surface 10 of the locking plate 6a of the retainer 6 is provided with a recess 12 into which the rib-shaped projection 11 is fitted. Even if the rib-shaped convex portion 11 is provided on the taper surface 9 on the back surface of the housing lance 4, since the rib-shaped convex portion 11 is not the entire surface of the taper surface 9,
There is no concern that the housing lance 4 will sink or warp after molding, and the insertion and holding of the terminal 3 will not be adversely affected.
