Connector

A connector comprising:

• a connector main body with a hook at one end, the connector main body including a housing hole formed so as to open toward a front end of the hook;
• a guide slot formed along the housing hole for communication between the housing hole and the exterior thereof;
• an opening-closing rod retained in said housing hole in movable relation toward and away from the front end of the hook, for openably closing a mouth of the hook;
• a spring placed in said housing hole for urging the opening-closing rod in a closing direction;
• and an outwardly protruding opening-operation body attached to the opening-closing rod through a coupling portion which slides in the guide slot,
• wherein the connector main body has a pair of retaining holes that are located on both sides of the hook base part, and a ring-shaped misoperation-preventive member made of an elastic wire rod, the misoperation-preventive member having its opposite ends formed into a pair of inwardly-bent engagement portions that are engaged in said paired retaining holes, respectively, and having its midway part configured to be movable in a direction from the front end of the hook toward the opening-operation body and vice versa in an in-contact/out-of-contact relation with them,
• wherein said paired engagement portions, as well as said paired retaining holes, are axially staggered with respect to each other, so that the midway part of the misoperation-preventive member can be urged in the direction from the front end of the hook toward the opening-operation body,
• and wherein the connector main body has a stopper for bringing the midway part of the misoperation-preventive member to a stop in a position close to the opening-operation body against an urgence on said misoperation-preventive member.
