Many metal pipes and rubber hoses are used in automobiles for flow paths for gasoline, air conditioning refrigerant, etc. It is required that these tube bodies be connected in a short time and easily even in a narrow space in order to shorten the assembly time. In order to meet this demand,
Japanese Patent Laid-Open Publication No. 1983 (1973) disclosed a tube connecting device in which a metal tube has an annular protrusion or groove on its outer periphery near one end, and this protrusion or groove can be used to attach a tube connecting device with a single touch. This is proposed in Publication No. -225290, etc. However, when used in equipment such as automobiles that constantly generate vibrations during use, if relative vibration occurs in the axial or radial direction between the metal tube and the tube connection device,
The O-ring inserted between the metal tube and the tube connection device to prevent fluid from leaking out may deform or wear out early, causing leakage. Furthermore, since the tube connecting device is used in many locations, it must be simple and inexpensive in structure.
