A protection wall (13) stands up from a rear end part of a housing main body (11) and restricts an operation of a disengaging portion (28) of a lock arm (12) by covering the disengaging portion (28). A detector (70) is made movable to a detection position by being pushed forward when the housing main body (11) is properly connected to a mating housing (50). Further, the detector (70) includes a rear portion (73) located behind the lock arm (12) and to be pushed when the detector (70) is moved to the detection position. A disengagement window (74) used to operate the disengaging portion (28) is formed on a position of the rear portion (73) behind the disengaging portion (28).
