<p>A pipe joint comprises a body (1) with both ends open, at least one of which is to be a pipe insertion port (10), a slender slidable cylinder (2) coaxially installed in the body (1) so as to slide therein in a certain range, its free end facing the pipe insertion port (10), and a holding cylinder (3) inserted between the main body (1) and the slidable cylinder (2) in such a manner to move freely back and forth. The main body (1) has a taper (11) diminishing toward the pipe insertion port (10). The holding cylinder (3) has a slit (30) open to the pipe insertion port (10) and an outside diameter slightly larger than the inside diameter of the pipe insertion port (10). When a pipe H is forcibly fitted on the slidable cylinder (2) the holding cylinder (3) moves toward the pipe insertion port (10) along with the pipe being pulled back and the pressure of its abutment against the taper (11) results in secure connection. For disconnection, the pipe is firstly pushed back inwardly of the body (1) so that the holding cylinder (3) no longer abuts the taper (11) A shaft (A) is then inserted through an opening (12) of the body (1) to engage a stopping part (31) of the holding cylinder (3) and thereby retain it while the pipe is drawn out and freed. <IMAGE></p> |
