An assembly for a drug delivery device (1) is proposed, comprising a housing(13) having a proximal end and adistal end, a dose member (23) which is displaceable in the proximal directionwith respect to the housing for setting of a dose of adrug, a clutch member (28) which is displaced in the proximal direction withrespect to the housing when setting the dose, and astop member (30) configured to define a clutch stop position for the proximaldisplacement of the clutch member with respect tothe housing, with the clutch member, when in the clutch stop position, beingprevented from further displacement in the proximaldirection with respect to the housing, wherein the clutch member and the dosemember are configured to mechanically cooperatewith one another when the clutch member is in the clutch stop position,thereby preventing further displacement of the dose memberin the proximal direction with respect to the housing during setting of thedose. Furthermore, a drug delivery device (1) isproposed.
