A first fragile part 46 provided at the outer connector 40 is destroyed and part of the outer connector 40, which is located below the first fragile part 46, is removed. Then, another part of the outer connector 40, which is located above the first fragile part 46, is pushed down to separate the engagement projection 42 from the projection fitting part 12.SELECTED DRAWING: Figure 2 |
