ABSTRACT:
The pipe joint connection, in which one of the pipes to be connected is inserted into the other pipe, has a click-stop arrangement for maintaining the connection, which click-stop arrangement comprises two stop webs extending conically with respect to each other and being mounted on the outside of one pipe and two resilient tongues mounted on the outside of the other pipe. When the two pipes are being connected, the resilient tongues pass between the stop webs, whereby they are moved towards each other and, when being in the stop location, engage with the backsides of the stop webs.
