PROBLEM TO BE SOLVED: To provide a circulation connector, a connecting structure of the circulation connector and a fuel circulating system, insertable into a fuel injection part by relatively weak force. SOLUTION: This circulation connector is used for the fuel circulating system for recirculating fuel to a fuel tank from the fuel injection part in an internal combustion engine having the fuel injection part, and is interposed between the fuel injection part and a fuel circulating hose, and is joined to the fuel injection part, and has a second groove part locked by a clip member together with a first groove part arranged in a connecting part in a state of being inserted into the connecting part of the fuel injection part and a tapered part having a diameter reducing in the inserting direction from the second groove part. An inclination in the inserting direction on the side near to the second groove part in the tapered part is set smaller than an inclination in the inserting direction on the side distant from the second groove part.
