PROBLEM TO BE SOLVED: To provide a connector which can prevent an opening/closing rod from moving toward an opening direction and prevent an opening part of a hook from opening by accident and can be easily manufactured.SOLUTION: A pair of locking holes 20 and 21 are arranged on two sides of a base part of the hook 2 of a connector body 3. A pair of engaging parts 26 and 27 bending inward and engaging with the pair of locking holes 20 and 21 are arranged on two ends of a malfunction preventing member 23. A middle part 23a of the malfunction preventing member 23 can move freely closer to and away from the front end of the hook 2 toward an opening operation body 13. The shaft centers of the pair of engaging parts 26 and 27 and the pair of locking holes 20 and 21 are staggered so that the middle part 23a of the malfunction preventing member 23 may be biased from the front end of the hook 2 toward the opening operation body 13. A stopper 28 which stops the middle part 23a of the malfunction preventing member 23 in a position close to the opening operation body 13 against biasing of the malfunction preventing member 23 is arranged on the connector body 3.【課題】 開閉ロッドが開放方向に移動してフックの開口部が不測に開くのを防止できると共に容易に製造することができる連結具を提供する。【解決手段】 連結具本体３のフック２基部の両側に一対の係止孔２０，２１が設けられ、誤作動防止部材２３の両端部に内方に屈曲されて前記一対の係止孔２０，２１に係合される一対の係合部２６，２７が設けられて、誤作動防止部材２３の中途部２３ａがフック２の先端側から開放操作体１３に向けて接離移動自在とされ、誤作動防止部材２３の中途部２３ａをフック２の先端側から開放操作体１３に向けて付勢するように、前記一対の係合部２６，２７及び一対の係止孔２０，２１はその軸心が互いにずらされ、誤作動防止部材２３の付勢に抗して誤作動防止部材２３の中途部２３ａを開放操作体１３に近接する位置で止めるストッパー２８が連結具本体３に設けられている。【選択図】図１
