The present disclosure relates to a connecting joint, including a connecting tube and a first compression sleeve. The connecting tube includes a first tube connecting section for connecting a first tube and a second tube connecting section for connecting a second tube. The first tube connecting section and the second tube connecting section are communicated and an annular connecting plate is arranged therebetween. The first compression sleeve is sleeved on the second tube connecting section. A first insertion hole with an annular cross-section for the second tube to be inserted into is formed between an inner wall of the first compression sleeve and an outer wall of the second tube connecting section. A first annular groove is formed in an outer surface of one end of the second tube connecting section close to the annular connecting plate. An end portion of one end of the first compression sleeve close to the annular connecting plate is bent toward the second tube connecting section and inserted into the first annular groove. The connecting joint provided by the present disclosure can simplify the connection of the connecting joint and the plastic tube and save installation time and is convenient to install.
