A fast pipe joint is composed of a sleeve and a main body. The sleeve is fitted over the main body such that an elastic piece extending upward from lower end of the inner edge of the sleeve is engaged with a retaining hole of the main body. The retaining hole is located in the channel of the main body. The main body is provided at the lower end thereof with a tubular body. The retaining portion of the elastic piece is engaged with the top of the retaining hole such that the inner edge of the retaining hole is urged by the retaining portion, so as to press against the tubular body located in the channel. When the sleeve is exerted on by a downward force, the sleeve is actuated to move downward, so as to enable the retaining portion to be retained in the bottom of the retaining hole to move out. The structure is thus simple and cost-effective. The structure can be quickly fastened or unfastened with the tubular body.
