A bell-clip type impact resistance water pipe is provided to restrict an inner periphery of a pipe joint from being broken, and to prevent leakage by flexibly moving the water pipe according to the gradient angle of an end part and a movable part in expanding or contracting the water pipe. A bell-clip type impact resistance water pipe(100) comprises a main pipe(110) and a pipe joint(120). An end(111) of the main pipe is tapered and inserted to the pipe joint of the other bell-clip type impact resistance water pipe. The pipe joint is composed of an end part(121), a rubber packing insertion part(122), a pipe moving unit(123), and a marginal part(124). The rubber packing insertion part is contacted to the outer periphery of the main pipe to improve sealing efficiency by inserting a rubber packing. Both ends of the rubber packing insertion parts are formed to be equal to an outer bore of the main pipe. The end part is connected to the rubber packing insertion part, and opened. The inner diameter of the opening portion of the end part is formed to be larger than the outer diameter of the main pipe. The end part and the pipe moving unit are inclined and connected to the rubber packing insertion part.
