A lock ( 35 ) is provided at the leading end of a resiliently deformable lock arm ( 33 ) on a female housing ( 20 ) and engages an engaging portion ( 14 ) on a male housing ( 10 ). An unlocking arm ( 40 ) is provided separate from the lock arm ( 33 ) and is resiliently inclinable like a seesaw. Projecting pieces ( 48 ) are formed on opposite surfaces of the lock ( 35 ) and unlocking pieces ( 49 ) on the unlocking arm ( 40 ) face the backsides of the projecting pieces ( 48 ). An operable portion ( 44 ) of the unlocking arm ( 40 ) is pressed to incline the unlocking arm ( 40 ) so that the unlocking pieces ( 49 ) lift the lock ( 35 ) of the lock arm ( 33 ), thereby canceling a locked state.
