Claims

[Scope of Claim for Utility Model Registration] 1. A connecting portion to be connected to a tube, a male connector connecting portion having a cylindrical periphery on one end surface, which has a tapered hole whose diameter becomes smaller inward from one end surface, and the tapered hole. The male connector has at least two latching protrusions formed on a cylindrical surface at the periphery of one end surface of the male connector connecting portion to protrude in a radial direction, and having a passage that is bored in the connecting portion from the deep end thereof and communicating with the tube. In a female connector for a medical tube, the latching protrusion has a cross-sectional shape along the outer circumferential surface of the connector, at least on the tube connection side, and the side is inclined outward by a predetermined amount toward one side adjacent to the side. A female connector for a medical tube characterized by an arc shape. 2. The female connector for a medical tube according to claim 1, wherein the locking protrusion has a tube connection side/side surface and both adjacent side surfaces connected to form a curved surface.
