While an operation of fitting a male connector housing (10) and a female connector housing (20) on each other is being performed, a connection locking piece (28) is disposed between elastic arms (32). The elastic arms (32) are prevented from elastically deforming inward or in a closing direction. Consequently an interference between a protection wall (29) and an outward projected part (37) is maintained, and the connection locking piece (28) interferes with an inclined surface (36A). The interference securely prevents the pressing operation of a fit-on detection member (30) forward from being performed. When the male connector housing (10) and the female connector housing (20) are normally fit on each other, the connection locking piece (28) is disposed away from the inclined surfaces (32A) and (36A). Thus, there is no interference between the protection wall (29) and the outward projected part (37) and between the connection locking piece (28) and the inclined surface (36A). In this state, an operator can perform the forward pressing operation of the fit-on detection member (30). Thus, the operator can securely detect that the male connector housing (10) and the female connector housing (20) are in the normal fit-on state.
