摘要： To realize compact packing without causing a tube kink in an extracorporeal circulation circuit of especially a pre-connecting type which uses tubes and connectors. A connector includes a first fitting member and a second fitting member into which ends of tubes are to be fitted, and a connecting member sandwiched between and connected with the first and second fitting members. The connecting member is constricted in the middle, thereby forming a thin-walled part that has a smaller wall thickness than the other parts of the connecting member which are closer to the first and second fitting members. The thin-walled part is continuously formed around a circumference of the connecting member.
