A device for mounting a needle guard on a syringe body which is provided with a needle, comprising:

• a retainer retaining the syringe body;
• a needle guard receptacle receiving the needle guard;
• a compressed-air device furnishing compressed air;
• a first displacement device moving the needle guard receptacle in a longitudinal direction with respect to the syringe body;
• and
• a rotation device for at least partially rotating the needle guard receptacle, wherein the needle guard receptacle is disposed below the retainer in the longitudinal direction, wherein the compressed air is supplied to the needle guard receptacle in such a way that the needle guard is held floating on an air cushion, and the needle guard receptacle is movable in the longitudinal direction by means of the first displacement device.
