PROBLEM TO BE SOLVED: To provide a freely breakable seal which is surely prevented from being broken against the intension. SOLUTION: A connector for medical treatment is provided with a connector 10 having an internal cone 11 for inserting an external cone 31 of a counter connector 30 and a freely breakable seal 18. for closing a duct 13. When screwing the counter connector 30 onto the connector 10, the freely breakable seal 18 is broken so as to facilitate the permeation of liquid through the connector 10. Since a rod 20 equipped with the freely breakable seal 18 is terminated inside the internal cone 11 at the position axially away from an inserting end 12, the rod 20 can reach only through the external cone 31 of the counter connector 30. |
