Needle protection device with a blocked protective position

A needle guard for an injection device, the needle guard comprising:

• a) an injection needle,
• b) a needle holder which is attached to or can be attached to the injection device, from which the injection needle extends in a distal direction,
• c) a lock mechanism which extends out from the needle holder and is spaced radially apart from the injection needle,
• d) and a needle guard member which can be moved radially between the injection needle and the lock mechanism in the proximal direction as far as a releasing position releasing the injection needle and out of the releasing position in the distal direction as far as a guard position in which it surrounds the injection needle, including a needle tip, and which can be locked in the guard position by the lock mechanism to prevent another movement in the proximal direction, and
• g) a locking member radially between the injection needle and the needle guard member and able to move relative to the injection needle from a proximal position in the distal direction, wherein
• h) the needle guard member has a locating element and the locking member has a complementary locating element, wherein the locating element and the complementary locating element move into a driving connection with one another when the needle guard member is moved into the releasing position, and the needle guard member drives the locking member with it in the driving connection during the movement into the guard position.
