Connector with plural housings accommodated in a casing

A connector, comprising;

• a plurality of separate housings, each said housing having opposite front and rear ends and being formed with a plurality cavities, extending between the front and rear ends, locks cantilevered forwardly into the respective cavities, each said lock being resiliently deflectable into a deformation permitting space open at the front end in the respective housing,
• a plurality of terminal fittings disposed respectively in the cavities of each of said separate housings and being locked in the respective cavities by the lock in the respective cavity, and
• a single casing having a main body and a plurality of inner tubular bodies, each said inner tubular body having opposite front and rear ends and an accommodation recess extending between the ends, each of the accommodation recesses being configured for receiving one of said separate housings such that the front end of the respective housing is in proximity to the front end of the inner tubular body and such that the rear end of the respective housing is in proximity to the rear end of the corresponding inner tubular body, the casing further comprising deformation restricting portions extending rearwardly from the front end of each said inner tubular body to a location between the front and rear ends of the inner tubular body, the deformation restricting portions extending into the deformation permitting spaces for restricting the deformation of the locks.
