1. An injection device comprising:
a housing having an axis; and
a needle sleeve that is axially movable within the housing, wherein an axial movement of the needle sleeve into the housing is configured to actuate an injection process,
wherein the needle sleeve comprises:
a first part slidably mounted to the housing,
a second part that protrudes from the housing and is rotatably coupled to the first part such that the second part can be rotated relative to the first part about the axis, wherein the second part is configured to be gripped by a user to rotate, and
a locking mechanism configured to prevent the axial movement of the needle sleeve into the housing until the second part of the needle sleeve has been rotated relative to the first part of the needle sleeve.
 
24. An injection device comprising:
a housing having an axis; and
a needle sleeve that is axially movable within the housing, wherein an axial movement of the needle sleeve into the housing is configured to actuate an injection process,
wherein the needle sleeve comprises:
a first part slidably mounted to the housing,
a second part that protrudes from the housing and is rotatably coupled to the first part such that the second part can be rotated relative to the first part about the axis, wherein the second part is configured to be pressed against an injection site to actuate the injection process, and
a locking mechanism configured to prevent the axial movement of the needle sleeve into the housing until the second part of the needle sleeve has been rotated relative to the first part of the needle sleeve.
