Abstract

A coupling element connects a connection piece with an insertable end of a connection tube having a toroidal flange for contacting the connection piece in the tube inserting direction. A plug-in fork can be inserted into the coupling element to releasably secure the inserted tube end area against the tube inserting direction, with the tube torus held in place by the plug-in fork. For this purpose, pairs of plug-through openings are provided on side walls of the connection piece opposite one another, so that one prong of the plug-in fork can be inserted into each opening. Inserting bevels are assigned to at least a portion of the plug-through openings, which inserting bevels are shaped such that they cause a forced movement of the plug in fork in the tube inserting direction during its insertion in the plug-in fork inserting direction.
