By simply fitting and holding the jig body into the harness draw-out port in the held state and engaging the retaining piece with the opening edge of the draw-out port, the connector half and the jig body are inserted into the harness draw-out port. This makes it possible to temporarily fix and protect the connector halves, so that there is no possibility that the connector halves will be damaged by being caught between the relatively displaced body parts or colliding with other objects. In addition, when it comes to the step of joining the connector half to the other connector half, it is only necessary to take out the jig main body from the harness draw-out port and simply pull out the connector half from the jig main body. The removal of the connector half can be performed extremely easily and quickly as compared with a case where the half is stored inside the vehicle body without a jig.

According to a second aspect of the present invention, in addition to the above feature of the first aspect of the present invention, when the one connector half is fitted to the peripheral wall of the concave portion of the jig body in the concave portion. A notch-shaped harness escape portion through which an end portion of the wire harness connected to the half body passes is formed. According to this feature, when the connector half is fitted into the concave portion of the jig body for the temporary fixing, the corresponding end of the wire harness is passed through the harness relief portion of the peripheral wall of the concave portion of the jig body. Therefore, the connector half can be smoothly fitted into the jig main body concave portion without forcibly bending or twisting the corresponding end portion of the wire harness without being disturbed by the corresponding end portion. Can be.

In a third aspect of the present invention, in addition to the above features of the first or second aspect, the first body portion is a pillar of an automobile, and the second body portion is a pillar of the vehicle. The door is hinged to the pillar and can open and close a side opening of the vehicle body. According to this feature, since the connector half can be easily temporarily fixed in the harness draw-out opening of the pillar, there is no possibility that the connector half is pinched between the door and the pillar when the door is closed and is damaged. If there is a considerable difference in height between the inner bottom of the pillar and the harness outlet, it is not easy to remove the connector half if it is dropped into the pillar. Since the connector half can be securely held in the harness draw-out opening by using the tool, it is very easy to take out the connector half.
