Abstract

One of the mating connector housings has a locking arm and the other connector housing has an engagement sleeve that receives the locking arm. The locking arm rises through a base at the front outer circumference of the first housing and extends axially rearwardly. The locking arm has guide means formed at the base. The engagement sleeve has engagement groove means formed in side walls thereof that extend axially from the front opening toward the rear and which receives the guide means. When the paired connector housings are connected together, the guide means of the locking arm are received into the engagement groove means in the engagement sleeve to prevent the weak portion of the connector housing formed with the locking arm from being deformed, thus providing a good locking feel and also an adequate engagement stroke. This makes the complete connection of the connector housings easily verifiable.

Claims
