A retainer ( 30 ) including a pair of side plates ( 32 ) is mounted such that the retainer ( 30 ) crosses over a housing ( 10 ) along width direction and the side plates ( 32 ) bulge out along width direction from side surfaces of the housing ( 10 ). Protection walls ( 27, 28 ) are formed on the side surfaces of the housing ( 10 ) to project around movable ranges of the side plates ( 32 ) of the retainer ( 30 ). Thus, inadvertent movement of the retainer ( 30 ) due to the contact of an external matter with the side plates ( 32 ) can be prevented. The protection walls ( 27, 28 ) are formed to define jig insertion holes ( 29 ). Thus, the side plates ( 32 ) of the retainer ( 30 ) can be disengaged from a full locking position by inserting a jig (J) through the jig insertion holes ( 29 ).
