Abstract
A tube to be connected to a pipe is formed of a base portion, a wide portion and a narrow portion integrally molded together. The wide portion has an inner end extending to the base portion, and an opening formed at a side opposite to the inner end. An inner diameter of the wide portion is greater than that of the base portion. When the pipe is inserted, the base portion receives an insertion portion of the pipe, while the wide portion receives a projecting portion of the pipe therein. The narrow portion deformably projects inwardly from an inner circumference of the wide portion at a position away from the inner end. The narrower portion allows the projecting portion to pass therethrough in a pipe inserting direction by deformation thereof, and prevents the projecting portion from passing therethrough in a pipe removing direction opposite to the pipe inserting direction.
