Infusion set

A catheter head for medical and pharmaceutical applications, including a base body which may be positioned on organic tissue and a connecting body, serving as fluid connector for the base body, which has a fluid channel to form the fluid connection. The base body and the connecting body are detachably connected to each other and the base body includes: a) a housing b) a cannula, extending from the housing for introduction into the tissue, c) a seal element, retained by the housing, which has a connector face on which or by means of which the fluid channel of the connecting body may be hydraulically connected to the cannula, and d) a closing element, mounted on the housing which may be displaced relative to the sealing element and seals the sealing face of the sealing element in a closed position and opens the connecting body for the fluid channel in an open position.
