A connector (6) for attaching a flexible tube to a fluid passage of another object includes a housing (17) and a connector port (45,46,47) on the body. The connector port (45,46,47) is sized and shaped for connecting the connector port in fluid communication with the fluid passage of the object. The connector (6) includes a tube port projecting from the body (17). The tube port is adapted for fluid communication with the connector port (45,46,47) and is sized and shaped for being received in an end of the flexible tube to establish fluid communication with the flexible tube. The tube port (11,12,13) includes a tube retainer (22) that projects from the body (17) toward the tube port. The retainer (22) has an engaging end portion disposed in relation to the tube port to engage the flexible tube when the tube port is received in the flexible tube. The flexible tube is restrained from lateral movement with respect to the tube port (11,12,13).
