Coupling of conduits with melted and solidified plastic material

A method of coupling at least two conduits for bringing them in communication, wherein each of the conduits is adapted for conducting a medium and comprises an outlet and an outer surface adjacent to the outlet, and at least one of the conduits comprises a light guide adapted for conducting and irradiating a fluid with light and at least one of the conduits is a fluid conduit adapted for conducting a fluid,

• the method comprising:
• inserting the outer surfaces at least partly and a solid plastic material into an aperture of a coupling element,
• heating the plastic material at least partly for at least one of:
• plastifying, melting,
• solidifying the plastic material for sealing and fixing the conduits within the aperture of the coupling element.

A coupling for bringing at least two conduits in communication, comprising:

• a coupling element with an aperture, and
• a plastic material or compound adapted for sealing and fixing the at least two conduits within the aperture,
• wherein each conduit comprises an outer surface and is adapted for conducting a medium,
• the aperture is adapted for receiving the plastic material and at least partly the outer surfaces of the conduits,
• the plastic material was heated for at least one of:
• at least partly plastifying, at least partly melting;
• and thereafter solidified, and
• at least one of the conduits comprises a light guide adapted for conducting and irradiating a fluid with light and at least one of the conduits is a fluid conduit adapted for conducting a fluid.
