ABSTRACT:
A pipe joint for connecting a rigid pipe with a retaining flange to a tube includes a pipe joint body formed with a through bore and a window in communication with the bore. A tube connector portion may be connected at an angle to a rigid pipe connector portion. A pipe retainer provided with locking pieces can be located in two positions relative to the pipe joint body. The first position allows the retaining flange to pass through the locking pieces. The second position retains the rear of the retaining flange and prevents inadvertent removal of the rigid pipe. The retaining pieces engage the rear of the flange through the window communicating with the bore. The locking direction of the retainer can be altered relative to the tube connector portion to suit different applications and ease assembly.
