A needle cover for covering an injection needle of an injection device, such as an injection pen, including a cover which can be shifted longitudinally along the longitudinal axis of the needle and which covers a proximal end of the needle in a needle protecting position, a restoring means for axially returning the cover from a retracted position towards the proximal end of the needle into an advanced position, and a latch for preventing the cover from being retracted in the needle protecting position, wherein the position of the cover is different in the advanced position and in the needle protecting position, and the latch is activated to prevent the cover from being retracted when the cover is shifted near to the needle protecting position. The present invention encompasses a cannula support comprising such a needle cover, wherein the needle cover is detachably or non-detachably connected to the cannula support.
