ABSTRACT:
A pipe joint is composed of a connection portion, two coupling handles and two auxiliary handles. The coupling handles and the auxiliary handles are fastened pivotally with two pivoting seats of the connection portion such that the coupling handles and the auxiliary handles are arranged side by side, and that the auxiliary handles can be actuated by the coupling handles in motion, and further that the auxiliary handles serve to avert the loosening of the connection portion at such time when the coupling handles are caught accidentally by a moving object or actuated accidentally by a person.
