To provide a connector.

In general, a pipe is simply used to connect a synthetic resin tube having irregularities repeatedly formed on the outer circumference such as a corrugated pipe (synthetic resin double wall pipe) or a spiral tube. Synthetic resin double walled pipe combined with shape-shaped packing is combined by interference insertion on both sides of the pipe to maintain a certain length.In the initial stage when the synthetic resin double walled pipe is combined, the sealing capacity is maintained somewhat, but the longer the mounting period, As the outer surface is oxidized and hardened, there is a problem that the sealing capacity is gradually decreased, and as the pressure of the circulating fluid increases, the sealing capacity and locking ability decrease, so that the fluid not only leaks, but also the problem of releasing the bonding state occurs. Done.
