An acupuncture device includes an acupuncture needle which has an elongate grip part with a substantially cylindrical main portion and a needle part which is fixed to the distal end of the grip part such that its longitudinal axis is aligned with the grip part and a guide tube which is open at both ends and whose lumen has a substantially cylindrical main portion and a releasable clamping device, by means of which the acupuncture needle is held in the condition of readiness for use inside the guide tube so that the grip part projects outwardly out of the proximal end of the guide tube while the distal end of the guide tube extends beyond the tip of the needle part. The grip part further has a portion which is thickened in relation to its main portion and the lumen of the guide tube has a narrowed portion which adjoins the proximal end of its main portion and whose smallest inside diameter is smaller than the largest outside diameter of the thickened portion of the grip part and larger than the outside diameter of the cylindrical main portion of the grip part, wherein the clamping device is formed by the thickened portion of the grip part and the narrowed portion of the lumen of the guide tube.
