ABSTRACT:
A connecting structure for piping members facilitates connection thereof and ensures prevention of liquid leakage. A first piping member includes a first channel, and at least one first joint surface in which at least one first opening communicating with the first channel and a first annular groove are provided. A second piping member includes a second channel, and at least one second joint surface in which at least one second opening communicating with the second channel and a second annular groove are provided. A sleeve for connecting the first and second piping members includes a central bore. The sleeve includes a pair of inserting sections and a partition therebetween. The inserting sections are thinner radially as compared to the partition and are configured to accommodate at least one elastic body which provides a seal when the inserting sections are press-inserted into the first and second annular grooves.
