Abstract
Abstract A lock arm is integrally formed on an outer surface of a connector housing of an insertable connector through a support leg and is engaged with a lock projection on a relay connector portion. A pair of protective walls are provided respectively on opposite sides of the lock arm and are spaced from the lock arm. The protective walls are disposed at a region corresponding to a gap between the lock arm and the connector housing. The front end portions of these protective walls are interconnected by a bridge portion. With this arrangement, a wire is prevented from being caught in the gap between the lock arm and the connector housing.
