The invention relates to an insertion head for medical applications, with a flexible cannula (5) supported by a puncture needle (15). In the state in which the insertion head is offered for sale, the puncture needle (15) and cannula (5) are arranged in a protected position inside two slideable housing halves (10, 12) of the insertion head and can be deployed, by gripping the housing (10, 12) and sliding the two housing halves (10, 12) together, such that it is possible to apply the insertion head by inserting the puncture needle (15) and the cannula (5) into the body of a patient. After application is completed, the puncture needle (15) can be removed from the cannula (5) and from the cannula housing (17b) carrying the latter, by means of the two housing halves (10, 12), with the puncture needle (15) held thereon, being moved away from the body counter to the direction of insertion. In doing so, the puncture needle (15) is held in the housing (10, 12) in such a way that, directly after emerging from the cannula housing (17b), it is automatically pivoted back by a spring force into a protected position in the housing (10, 12). Such an insertion head according to the invention is simple and safe to use.
