PROBLEM TO BE SOLVED: To prevent the generation of unexpected opening of a connector by forming a blocking means as single part formed of a mouth-piece blocking element of a housing area, a manual control part for controlling the opening of the connector, and a snap element on levers having an elastic load. SOLUTION: When fins 10, 10' are pulled for opening, levers 3, 3' are rotated, and a line for connecting points 16, 16' and positioned under the center 4 coincides with a working line of a metal wire 15 on the levers 3, 3', and the levers 3, 3' are opened by the force of FA, and contact with stop pins 13, 13', and crosspieces 8, 8' open a front mouthpiece 5 of a rigid main body 2. When a material hooked on the connector 1 pushes a part over from the mouthpieces 5 to tips of fins 9, 9', the levers 3, 3' are rotated, and the line for connecting the points 16, 16' is moved to a position over the center 4, and the cross-pieces 8, 8' constrain the material within a housing area 6. Rotation of the levers 3, 3' is stopped when flaps 14, 14' are engaged with pins 12, 12. With this structure, opening of the connector due to the friction and impact can be prevented. |
