The disclosure further relates to an autoinjector and a method of assembling the autoinjector. A syringe carrier is disclosed comprising a housing adapted to receive a syringe. They syringe includes a needle encapsulated by a removable protective needle sheath. The syringe carrier further includes two or more flexible arms protruding outwards in a relaxed state and adapted to couple with the syringe in a mounted position.
