ABSTRACT:
When male and female connector housings 1 and 11 are in a half-fitted state, a spacer insertion groove 24 located at a posterior end of a locking arm 20 does not fully open. In order to prevent forcible insertion of a spacer, the insertion ends 33 of a spacer 30 have an inclined lower face, to reduce or eliminate a force tending to push up the locking arm 20. Even in the case where the first insertion ends 33 are forcibly inserted into half-fitted connector housings 1 and 11, complete insertion is prevented because a second insertion member 38 of the spacer 30 and the position of a through hole 23 are not aligned. Half fitting is thus reliably detected.
