1. An insertion device, comprising:
- a cannula;
a protective element for accommodating the cannula in a retracted position;
an energy storing element for expelling the cannula out of said protective element; and
a base body removably connected to the protective element;
wherein in the retracted position the cannula is positioned spaced apart from the base body; and
wherein when the energy storing element is released, the cannula is expelled from the protective element through an opening in the base body and is secured to the base body and wherein the cannula and base body, together, can then be disconnected from the protective element.
