Claims

[Scope of utility model registration request]

In a tubular connector that connects a first fluid conduit and a second fluid conduit to each other, the valve seat is made of a combination of a first tubular part and a second tubular part, and has a fluid passage hole. Provided integrally with the tubular part,
A valve body is attached to the valve seat, which can take either a contracted state in which the fluid passage hole is opened or an expanded state in which the fluid passage hole is closed due to a volume change due to fluid pressure. tubular connector.
