Abstract
The present disclosure pertains to an assembly for a drug delivery device having a housing part, a piston rod displaceable relative to the housing part, a first sleeve member and a second sleeve member. First and second sleeve members are coupled to the housing part. In an initial state of the assembly the first sleeve member is movable from an initial position to a second position relative to the second sleeve member which allows the piston rod to axially travel from an initial position to a predetermined second position such that the assembly is in a primed state. Moreover, in the primed state of the assembly, with the first sleeve member being in the second position relative to the second sleeve member, first and second sleeve members are permanently rotationally and axially locked to each other by a first engagement feature such that first and second sleeve members together form a sleeve.
