A connection device for use in the negative pressure therapy of wounds, includes a flexible conduit having at least two lumens and being constructed for impingement with negative pressure and/or fluid media； a coupling body made of an elastomeric flexible material, and non-detachably molded onto a wound-side end section of the conduit and being constructed for arrangement on a negative pressure bandage which covers the wound and seals the wound against the atmosphere, wherein the conduit communicates with a wound space through at least one opening in the coupling body； and a fluid inlet section for insertion through an opening in the negative pressure bandage into the wound space. The fluid inlet section is formed on the coupling body and protrudes over a walling of the coupling body, which walling faces the negative pressure bandage. The fluid inlet section is fluidly connected interiorly of the coupling body with a further lumen for delivering a fluid medium. The further lumen is formed inside the conduit or by a fluid delivery line leading to the coupling body.
