When the rear holder 1 having the above-described configuration is assembled, as illustrated in FIGS. 3, 5, the three electric wires 11 are situated between the lower member 1A and the upper member 1B, and the lower member 1A (or the upper member 1B) is moved close to each other so as to bring the lower side split surface 10A and the upper side split surface 10B into proximity with each other.

As the movement proceeds, the tip of the right-side lock piece 81A of the first electric wire insertion portion 3A comes into contact with the right-side contact surface of the right-side lock receiving-portion 82A, and as the movement further proceeds, the right-side lock piece 81A is situated between the first front side overhang portion 84 and the first rear side overhang portion 85. As a result, the right-side lock piece 81A becomes immovable in the longitudinal direction X between the first front side overhang portion 84 and the first rear side overhang portion 85, and the right-side lock piece 81A locks to the right-side lock receiving-portion 82A.

As the movement proceeds, the tip of the left-side lock piece 91A of the first electric wire insertion portion 3A comes into contact with the left-side contact surface 93 of the left-side lock receiving-portion 92A, and as the movement further proceeds, the left-side lock piece 91A is situated between the second front side overhang portion 94 and the second rear side overhang portion 95.

Furthermore, like the first electric wire insertion portion 3A, the second electric wire insertion portion 3B is such that the tip of the right-side lock piece 81B of the second electric wire insertion portion 3B comes into contact with the right-side contact surface of the right-side lock receiving-portion 82B so that the right-side lock piece 81B locks to the right-side lock receiving-portion 82B, and the tip of the left-side lock piece 91B comes into contact with the left-side contact surface 93 of the left-side lock receiving-portion 92B so that the left-side lock piece 91B locks to the left-side lock receiving-portion 92B.

Furthermore, like the first electric wire insertion portion 3A, the third electric wire insertion portion 3C is such that the tip of the right-side lock piece 81C of the third electric wire insertion portion 3C comes into contact with the right-side contact surface of the right-side lock receiving-portion 82C so that the right-side lock piece 81C locks to the right-side lock receiving-portion 82C, and the tip of the left-side lock piece 91C comes into contact with the left-side contact surface 93 of the left-side lock receiving-portion 92C so that the left-side lock piece 91C locks to the left-side lock receiving-portion 92C.

As a result, each electric wire 11 is sandwiched in the up-and-down direction between the upper side insertion portion 7 and the lower side insertion portion 6. In this manner the electric wire insertion portions 3A, 3B, 3C (3) are assembled, and the rear holder 1 in which the three electric wires 11 are supported is assembled.

When the rear holder 1 is attached to the connector housing, the rear holder 1 comes close to the connector housing in such a state that the three electric wires 11 are inserted through the inside of the connector housing and the rear holder 1 is situated on the rear side X2 of the connector housing, and the lower member 1A and the upper member 1B are assembled and attached to the connector housing simultaneously. In this manner, the rear holder 1 is attached to the connector housing.

According to the above-described embodiment, the lock portions 8A, 8B, 8C (8), 9A, 9B, 9C (9) for attaching the lower side insertion portion 6 (first insertion portion) and the upper side insertion portion 7 (second insertion portion) to each other are provided, and the lock portions 8, 9 include lock pieces 81A (91A), 91B (81B), 81C (91C) protruding from one of the lower side insertion portion 6 and the upper side insertion portion 7 to the other thereof, and lock receiving-portions 82A (92A), 92B (82B), 82C (92C) provided on the other of the lower side insertion portion 6 and the upper side insertion portion 7 to lock the lock pieces 81A (91A), 91B (81B), 81C (91C) immovably in the longitudinal direction X (direction in which the electric wires 11 extend), so that even if a local load is applied to only one of the lower member 1A and the upper member 1B (the two members), the lower member 1A and the upper member 1B are restricted from displacing relatively in the longitudinal direction X, and the lower member 1A and the upper member 1B are assembled and attached to the connector housing simultaneously. Therefore, when attached to the connector housing, it can be prevented to attach only one of the lower member 1A and the upper member 1B to the connector housing, so that ease of attachment to the connector housing is improved.

Furthermore, the lock portions 8, 9 include the lock piece 81A (91A), 91B (81B), 81C (91C) protruding from one of the lower side insertion portion 6 and the upper side insertion portion 7 to the other thereof, and the lock receiving-portions 82A (92A), 92B (82B), 82C (92C) provided on the other of the lower side insertion portion 6 and the upper side insertion portion 7 to lock the lock pieces 81A (91A), 91B (81B), 81C (91C) immovably in the longitudinal direction X (direction in which the electric wires 11 extend), so that even if a local load is applied to only one of the lower member 1A and the upper member 1B (the two members), the load is transmitted from the lock pieces 81A (91A), 91B (81B), 81C (91C) to the lock receiving-portions 82A (92A), 92B (82B), 82C (92C) and is dispersed throughout the entirety of the lower member 1A and the upper member 1B, so that the strength against pull-out load is improved.
