A connection tool of drainpipes is provided to readily connect the drainpipes and to improve water-tight performance of the connected drainpipes, that is, sealing force of the connected drainpipes. A connection tool of drainpipes comprises two drainpipes, a fastening band, a fixing socket(13), and a fixing ring(15). The two drainpipes are connected to each other in parallel. The fastening band connects the two drainpipes. The drain pipe has mounting grooves, into which the fastening band is inserted, formed at both ends thereof. The drain pipe is inserted into the fixing socket. The fixing socket is formed at an inner surface of the drain pipe. The fixing socket has a coupling groove coupled with the drainpipe. The fixing ring is installed at an inner surface of the coupling groove to allow the drainpipe to be tension-supported. The fixing ring has a slit groove formed at an inner surface thereof in a longitudinal direction thereof.
