The present disclosure relates to an injection device for setting and injecting a dose of a medicament, the injection device comprising: - an elongated housing (10) extending along a longitudinal axis (z) and having a distal end (41) and a proximal end (42), a dose tracker (50; 150; 250; 350; 450; 550) being at least one of translationally or rotationally displaceable relative to the housing (10) and being displaceable between a zero dose positional state (52) and a maximum dose positional (54) state relative to the housing (10) for setting of the dose, wherein the positional state (52, 54) of the dose tracker (50; 150) relative to the housing (10) is indicative of a size of the dose, wherein one of the elongated housing (10) and the dose tracker (50; 150; 250; 350; 450) comprises at least one tracking stop feature (51; 151; 251; 351; 451; 551 ), a preselector (70; 170; 270; 370; 470; 570) displaceable relative to the housing (10) between at least two preselection positional states (72, 74) thereby defining the maximum dose positional state (54) of the dose tracker (50; 150; 250; 350; 450; 550), wherein the preselector (17; 170; 270; 370; 470; 570) comprises at least one preselector stop feature (71; 171; 271; 371; 471 ) configured to mechanically engage with the at least one tracking stop feature (51; 151; 251; 351; 551 ) to block a displacement of the dose tracker (50; 150; 250; 350; 450; 550) beyond the maximum dose positional state (54).La présente invention concerne un dispositif d'injection pour définir et injecter une dose d'un médicament, le dispositif d'injection comprenant : - un logement allongé (10) s'étendant le long d'un axe longitudinal (z) et ayant une extrémité distale (41) et une extrémité proximale (42), un suivi de dose (50 ; 150 ; 250 ; 350 ; 450 ; 550) étant au moins déplaçable par translation ou par rotation par rapport au logement (10) et étant remplaçable entre un état de position de dose zéro (52) et un état de position de dose maximale (54
