Claims

[Scope of utility model registration request]

A ring-shaped flange plate is slidably fitted near the pipe end of one of the pipes to be connected, and a pair of ring-shaped protrusions integral with the one pipe is provided on the pipe end side of the flange plate. At the same time, an O-ring is attached to the outer periphery of one of the tubes between the pair of ring-shaped protrusions, and the reduced diameter part on the rear end side of the connecting tube is slidably fitted to the other tube to be connected. At the same time, a pair of ring-shaped protrusions are formed on the tube end side of the other tube, and an O-ring is provided on the outer periphery of the other tube between the pair of ring-shaped protrusions. The connecting tube has an inner diameter that allows it to come into close contact with the O-ring attached to the one tube and the O-ring attached to the other tube, and the connecting tube has a size that allows it to fit tightly to the O-ring attached to the one tube and the other tube, and the connecting tube has a terminal that fits into the one tube. A flange portion having approximately the same diameter as the flange plate is formed, and a pair of arcuate locking portions having a shape capable of holding the flange plate and the flange portion of the connecting pipe at the same time are integrally connected via a gripping portion. The locking device has a spring elasticity, and when the one pipe and the other pipe are brought into contact with each other, the connecting tube is slid to cover up to one pipe, and the flange plate and the flange of the connecting tube are connected. A pipe connecting device, characterized in that the locking tool is removably fitted to the flange plate of the connecting tube and the flange portion of the connecting tube.
