Claim:
1. A device for administering a cannula comprising: a basic element having a structure such that a tip of the cannula protrudes beyond the basic element in a ready to use position of the device, a traction element which is movable with respect to the basic element, a releasable pretensioning device for pretensioning the traction element with respect to the basic element in the ready to use position of the device, at least one actuating element formed on the basic element for releasing the pretensioning device, the at least one actuating element movable in a direction at a right angle to the cannula, wherein the at least one actuating element comprises a first gripping surface that is arranged at a side of the basic element, the at least one actuating element adapted to be actuated by pressing at least the first gripping surface of the at least one actuating element in the direction at the right angle to the cannula towards a central axis of the cannula, and the traction element being separate from and movable away from the at least one actuating element, the at least one actuating element including a first actuating element movable in the direction at the right angle to the cannula towards the central axis of the cannula and having said first gripping surface which is freely open and accessible by a first finger of a hand of a person, one of: at least one closing element mounted to the basic element for hiding the tip of the cannula, when the tip has been retracted into the basic element, wherein the at least one closing element is held at the basic element in such a way, that the at least one closing element is movable relative to the basic element such that the at least one closing element is moved relative to the basic element to a position in front of the tip of the cannula, and such that the tip of the cannula is hidden in the basic element, by pressing said at least one actuating element in the direction at the right angle to the cannula towards the central axis of the cannula, wherein a movement of the at least one actuating element in the direction towards the central axis of the cannula causes movement of the at least one closing element to said position in front of the tip of the cannula that has been retracted into the basic element, wherein the traction element interacts with the cannula so that, when the pretensioning device is released, the tip of the cannula retracts into the basic element, and wherein the device is designed for a one-handed operation for holding the basic element and releasing the pretensioning device, while the basic element is resting on skin of a patient.
