CONNECTOR AND WIRE HARNESS

A connector (1) applied to a wire harness includes a housing (2) housing a terminal (T), a front holder (4) assembled to an end portion in an axial direction (X) of the housing (2), and a restriction member (5) assembled to the housing (2). One of the housing (2) and the front holder (4) has a latch claw portion (81) that latches the housing (2) and the front holder (4). The other of the housing (2) and the front holder (4) has a latch arm portion (82) extending along the axial direction (X) and latched to the latch claw portion (81). The restriction member (5) has a restriction piece (54) that is located adjacent to the latch arm portion (82) that is in a state of being latched to the latch claw portion (81), the restriction piece (54) restricting displacement of the latch arm portion (82) toward a latch release side.
