A syringe carrier(16) comprising: a housing(16.0) adapted to receive a syringe (3) having a needle (4) encapsulated by a removable protective needle sheath (5) two or more flexible arms (16.1) protruding inwards in a relaxed state and adapted to couple with the syringe (3) in a mounted position wherein the flexible arms (16.1) are adapted to deflect radially outwards in a pre assembled position of the syringe (3) in the syringe carrier (16) wherein in the mounted position the flexible arms (16.1) are allowed to return into the relaxed state due in part to an axial force (F2) operating on the syringe carrier (16). The invention further relates to an autoinjector and a method of assembling the autoinjector.
