A needle guard device for or on an injection device, the needle guard device including: a) an injection needle, b) a needle holder which is or can be fixed to the injection device and from which the injection needle projects in a distal direction, c) a blocking device which projects from the needle holder and is radially spaced from the injection needle, d) a needle guard, and e) a return member which exerts on the needle guard an elasticity force operative in the distal direction, wherein f) the needle guard is moveable radially between the injection needle and the blocking device in the proximal direction into a release position freeing the injection needle and out of the release position in the distal direction into a guard position in which it surrounds the injection needle including a needle point, g) and which can be blocked by means of the blocking device in the guard position against renewed movement in the proximal direction, wherein h) a securing member (10; 15) is arranged between the injection needle and the needle guard moveably relative to the injection needle from a proximal position in the distal direction, i) the needle guard has an engagement element and the securing member has a counterpart engagement element which comes into entrainment engagement with each other when the needle guard is moved into the release position, j) and the needle guard in the entrainment engagement entrains the securing member (10; 15) upon the movement into the guard position, characterised in that k) the entrainment engagement is a latching engagement in which the engagement element engages behind the counterpart engagement element in relation to the distal direction. a) an injection needle, b) a needle holder which is or can be fixed to the injection device and from which the injection needle projects in a distal direction, c) a blocking device which projects from the needle holder and is radially spaced from the injection needle, d) a needle guard, and e) a return member which exerts on the needle guard an elasticity force operative in the distal direction, wherein f) the needle guard is moveable radially between the injection needle and the blocking device in the proximal direction into a release position freeing the injection needle and out of the release position in the distal direction into a guard position in which it surrounds the injection needle including a needle point, g) and which can be blocked by means of the blocking device in the guard position against renewed movement in the proximal direction, wherein h) a securing member (10; 15) is arranged between the injection needle and the needle guard moveably relative to the injection needle from a proximal position in the distal direction, i) the needle guard has an engagement element and the securing member has a counterpart engagement element which comes into entrainment engagement with each other when the needle guard is moved into the release position, j) and the needle guard in the entrainment engagement entrains the securing member (10; 15) upon the movement into the guard position, characterised in that k) the entrainment engagement is a latching engagement in which the engagement element engages behind the counterpart engagement element in relation to the distal direction.
