Abstract

The invention relates to a device for subcutaneous administration of a medicament to a patient, comprising a cannula housing (1) with an interior chamber; a cannula (2) connected to the cannula housing (1) and being in flow communication with the interior chamber; a tubing (4) manufactured from a flexible material and having a first end (4′), coupled to the cannula housing (1) in such a manner that the tubing (4) is in flow communication with the interior chamber; and wherein the tubing (4), at the other end, carries a source coupling (5), by which the tubing can be coupled to a source for said medicament. The invention is characterised in that, at least over a section of its length, the tubing comprises a longitudinally extending, external groove (12) and a longitudinally extending, external protrusion (11) arranged diametrically opposite the groove (12) and complementary with said groove (12); and that, using the flexibility of its material, the groove (12) is configured for being able to receive and secure the protrusion (11) in a releasable manner in a configuration of the tubing (4), in which the tubing (4) is folded (9) for forming parallel courses of tubing (14, 24, 34). The invention also relates to a tubing configured for use in said device.
