A water supply pipe connection device using a flexible band and a wire is provided to tightly connect water supply pipes by permitting a plurality of connection bars for connecting a first coupling and a second coupling to have constant pressures. A water supply pipe connection device(100) comprises a first coupling(110), a second coupling(120), a pair of sealing pipes(130), a flexible band(140), a plurality of connection bars(150), and a joint band(160). The first coupling is fitted to one end of a water supply pipe(10), and includes a connection frame(112) and a joint frame(113) which are opposed each other with an installation groove(116) therebetween. The connection frame has an inner surface with a plurality of first guides(111) and an outer surface with a plurality of through holes(114). The joint frame has a plurality of connection holes(115). The first coupling has one side with a first connection pipe(117). The second coupling is fitted to the other end of the water supply pipe, and has an inner surface with a plurality of second guides(121), an outer surface with an installation frame(123) having a plurality of joint holes(125), and the other surface with a second connection pipe(127). The sealing pipes are inserted into the first connection pipe and the second connection pipe, and have inner surface with a plurality of guide protrusions(131) and one surface with protrusions(133) contacting an end of the water supply pipe. The flexible band is fitted to outer surfaces of the sealing pipes, and has an interior with a wire(141). The connection bars have one ends coupled to the joint holes and the other ends with outer surface where gear portions(151) are formed. The joint band is inserted in the installation groove so as to rotate the connection bars at the same time and couple the connection bars to the joint holes.
