Abstract
A needle protecting device including: a sleeve-shaped base body which may be connected to a casing of the injection device or is formed by a casing of the injection device, a needle protecting sleeve which is mounted on the base body, wherein, in a proximal protective position, the needle protecting sleeve surrounds an injection needle of the injection device and, in a distal position, exposes the injection needle, a first block and a second block, one of which is connected non-sliding to the needle protecting sleeve and the other of which is connected non-sliding to the base body, wherein, in the protective position of the needle protecting sleeve, a blocking mesh is formed by the blocks pushing axially against each other and so preventing the needle protecting sleeve from sliding into the distal position, and a safety-release for releasing the blocking mesh, wherein the first block is formed by an elastically bendable latch which is connected rigidly to one of the needle protecting sleeve and the base body; and the blocking mesh of the blocks is released by bending the latch against a restoring force generated in the latch.
