A pipe connector has a tube and two binding rings. The tube is made from a soft material and forms at least one fixing segment on two ends. The two binding rings are mounted on the two ends of the tube respectively. Each binding ring has at least one locating segment. The amount of the at least one locating segment is equal to the amount of the at least one fixing segment of the tube. The at least one fixing segment engages with the at least one locating segment to fix the binding ring and the tube. Thus, a user only needs to expand the tube to mount the tube onto a water pipe instead of heating it. Alternatively, engaging the fixing segment with the locating segment prevents the binding ring from moving relatively to the tube.
