An insertion head for medical or pharmaceutical applications includes a base having a lower side which can be positioned on organic tissue; an insertion means movably mounted by the base and insertable into the tissue; where the insertion means is movable relative to the base from a protective position in which a free end of the insertion means is short of the lower side of the base, into an insertion position in which the free end protrudes beyond the lower side; a handle which projects from the base and includes a first handle component and a second handle component movable relative to the base and the first handle component; and a coupling that transmits a movement of the second handle component into a movement of the insertion means.
