Male connector

A male connector to be provided at an upstream end of a tube used in enteral feeding, the male connector comprising:

• a luer portion;
• and a lock portion that is removably attached to the luer portion,
• wherein the luer portion includes a base end portion suitable to be connected to the tube and a tubular male luer that is provided on the base end portion and in which a channel in communication with the tube is formed,
• the lock portion includes a lock portion body and two or more bar-shaped extension portions, and the lock portion body has a hollow tubular shape and is open at two ends and includes female threading that opposes the male luer on an inner circumferential face of the lock portion body, and the bar-shaped extension portions are formed integrally with the lock portion body and extend parallel to a lengthwise direction of the luer portion from an end of the lock portion body,
• when the lock portion is attached to the luer portion, the male luer is inserted into the lock portion body, and the bar-shaped extension portions of the lock portion are arranged radially outward relative to the base end portion of the luer portion so that the bar-shaped extension portions cover part of an outer circumferential face of the base end portion of the luer portion and expose a remaining part thereof,
• rotation prevention mechanisms that engage with one another are provided on the luer portion and the lock portion such that the lock portion does not rotate relative to the luer portion and
• a male tapered face formed on the luer portion and a female tapered face formed on the lock portion come into direct contact with each other and fit together such that a liquid-tight seal is formed between the luer portion and the lock portion at a position on a tube side relative to the male luer.
