That is, in the normal state, the temporary fixing portion 18
The protrusion amount is set so that the protrusion 33 of the second connector 4 and the protrusion 34 of the second connector 4 do not interfere with each other. When the connectors are connected, the second connector 4 can be connected to the second connector 4 without being disturbed by the detachment prevention mechanism. One connector 2 can be externally fitted and connected. Then, the projecting portion 28 of the second connector 4 comes into contact with the projection 29 of the temporary fixing portion 18, and the distal end portion of the temporary fixing portion 18 is pushed outward. As described above, at the stage before the protrusion 19 of the first connector 2 gets over the protrusion 18c of the temporary fixing portion 18, the protrusion 33 and the protrusion 34 interfere with each other to prevent the second connector 4 from being detached, and First
When the connector 2 moves to the coupling standby position shown in FIG. 21 and the pushing state of the temporary fixing portion 18 is released, the interference between the projecting portion 33 and the projection 34 is released, and the second connector 4

The second connector 4 may be configured to provide a pull-out resistance. In the case of such a configuration, as shown in FIG. 24, even if the second connector 4 is pulled obliquely at the time of the above-described uncoupling operation, the first connector 2 is obliquely oriented accordingly. Thus, the disconnection between the first connector 2 and the second connector 4 can be effectively prevented.

That is, when the second connector 4 is pulled obliquely as described above, and without the restricting portion 44, the second connector 4 is disconnected when the one end 4a of the second connector 4 is detached from the holder 1. Since the pull-out resistance of the first connector 2 is reduced, it is inevitable that the first and second connectors 2 and 4 are detached and the first connector 2 is left obliquely. On the other hand, in the case where the restriction portion 44 is provided so as to provide a pull-out resistance to the second connector 4, even if the one end 4 a of the second connector 4 is detached from the holder 1, The first connector 2 and the second connector 2 are controlled by the regulating portion 44 located at the center in the width direction of the connector 4.
