摘要：

PROBLEM TO BE SOLVED: To provide a gastrostomy tube set, easy to use and clean, having little risk of contamination and improved in sealing performance between a valve and a connector.

SOLUTION: The valve 3 includes: a cylindrical part 21 cylindrically projected from a hub 9 of a tube to the outside, the tip of which is provided with an opening 23 a flange 24 formed on the outer periphery of the cylindrical part 21, a part of which is provided with a cutout 25 a thin film 28 blocking up the opening 23 and having elasticity and a slit 29 formed in the thin film 28. The connector 4 includes: an inner cylinder part 36 pushing open the slit 29 to be inserted into the cylindrical part 21 an outer cylinder part 37 formed cylindrically in the periphery of the inner cylinder part 36 with a gap to which the cylindrical part 21 and the flange 24 are fitted and a lug 38 projected from the inner periphery of the outer cylinder part 37 largely enough to pass through the cutout 25 of the flange 24 and engaged with the flange 24 by rotating the connector 4 around the axis of the inner cylinder part 36 after passing the cutout 25 to prevent the connector 4 from slipping off the valve 3.
