A device (10) for at least partially inserting a needle (16) into the body of a patient is disclosed. The device (10) comprises a connector adapted for attachment to a needle (16), and a guard member (18) having a guide surface adapted to rest against a surface of the skin. The connector is adapted to set an attached needle (16) with a fixed position relative to the guard member (18), such that movement of the guide surface along the surface of the skin at least partially inserts the needle (16) into the body.
