Abstract
A water pipe connection device includes a connecting tube, a fastening member, and a fixing unit. The connecting tube includes a tapering tube head and a tubular member. The fastening member is disposed in the tube head. The fixing unit is disposed in the tube head, and includes a fixing ring and a plurality of reverse toothed structures. A water pipe is clamped and positioned by teeth portions of the reverse toothed structures. When the water pipe connection device is in use, water flows into the tube head through a space between the tubular member and the water pipe, and the fastening member is pushed by the water to move the fixing unit towards a tapered end of the tube head, so that the fixing unit is pressed by the tube head to fix the water pipe.
