A tubular coupling element for producing a glued joint with a fluid line and a method for producing such a glued joint. The coupling element includes an inner tube that is insertable into a fluid line and an outer tube that is constructed concentric to the inner tube and integrally connected to the rear end of the inner tube by a connecting wall. An annular gap is present between the two tubes and is designed to receive an end section of the fluid line and a hot-melt type adhesive in a compacted solid form shaped as a ring. A connection between the coupling element and the fluid lines can be easily established by first introducing the adhesive in the annular gap and then melting it by rapidly supplying heat while the end section of the fluid line is pressed into the annular gap of the coupling element.

A rotatable stopcock for a plug-type coupling with an angled piece for connecting fluid lines. The stopcock including a turning knob portion and an integrally formed hollow pin portion. The knob portion includes two opposing ring segments having detent catches that positively engage a flange ring formed on the coupling housing wall. The pin portion is dimensioned to be received into a contact hole of the plug-type coupling such that rotating the stopcock after insertion causes the hollow pin portion to regulate the fluid flow through the plug-type coupling.

A connection unit of a releasable quick coupling that includes a cylindrical housing head, connecting sleeve, support sleeve and a ceiling ring. The cylindrical housing head defines a receiving space and includes a retaining element having movable edges that are directed into the receiving space. A tubular inserting part having a encircling retaining rib is insertable into the receiving space such that the retaining rib is engaged by the retaining element. The connecting sleeve is molded an end of the housing head and is adapted to be inserted into the end of the pipeline. The body of the connecting sleeve and detents of the housing head form a mounting space that is adapted to receive and secure an edge of the pipeline. Additionally, a support sleeve is mounted on the connecting sleeve at a second end opposite said housing head. Finally, a sealing ring is disposed within the support sleeve.
