PURPOSE: A one-touch type coupler for a pipe is provided to prevent release of bending against hydraulic pressure by forming the bending portion with bending the end of the pipe connection part inward, and to restrict movement of the pipe by supporting the pipe in the small diameter part, the sleeve and the inside of the bending part. CONSTITUTION: A bending part(33) is formed in the end of a pipe assembling part(32) to prevent displacement of a sleeve(60), and bent inward at 180 angular degrees to be integrated with the outer diameter of a pipe. The pipe assembling part includes a small diameter part(34) equal to the outer diameter of the pipe, a middle diameter part(35) expanding from the small diameter part and placing a snap ring(40) and an O-ring(50), and a large diameter part(36) expanding from the middle diameter part and placing the sleeve to insert the snap ring preventing displacement of the pipe, the watertight O-ring and the sleeve sequentially.
