A syringe holder for an autoinjector is presented having a tubular body extending around an axis in a circumferential direction and along the axis in an axial direction, the tubular body having a cut-out extending from a distal end of the tubular body and a flexible expansion joint extending across the cut-out in the circumferential direction. The tubular body can also have an inner surface and an outer surface, a first cut-out in the tubular body, the first cut-out extending in an axial direction from a proximal end of the tubular body and either a recess in the inner surface of the tubular body, the recess extending in the axial direction from the distal end of the tubular body, or a second cut-out in the tubular body, the second cut-out extending in the axial direction from a distal end of the tubular body.
