Syringe connector for a medicament delivery device

A syringe connector for a medicament delivery device, the syringe connector comprising:

• a main body having a longitudinal axis, the main body comprising a first wall extending transversely to the longitudinal axis, an opposing second wall extending transversely to the longitudinal axis, and a side wall connecting the first wall and the second wall, the first wall and the second wall defining a cavity configured to receive a proximal end of a syringe,
• wherein the cavity comprises a syringe flange receiving portion located between the first wall and the second wall and delimited by the side wall, and a syringe body receiving portion formed by an aperture extending through the second wall, and
• wherein the cavity extends to an opening in the side wall and an edge of the second wall such that a proximal end of a syringe can be inserted transversely into the cavity;
• a syringe retention element configured to restrict radial movement of the syringe when the syringe is located in the syringe connector, wherein the syringe retention element comprises a pair of arms that project radially inward from the side wall into the syringe flange receiving portion of the cavity, the pair of arms being positioned longitudinally between the first wall and the second wall and separate from both the first wall and the second wall, each arm of the pair of arms having a bottom surface positioned proximally relative to a top surface of the second wall along the longitudinal axis and spaced from the top surface of the second wall by a gap such that the arm is deflectable in a radial direction within the syringe flange receiving portion;
• and
• an impact force reduction element configured to reduce force transmitted to the syringe when a dispensing mechanism is triggered during use.

A method of forming a syringe connector for a medicament delivery device, the method comprising:

• positioning a plurality of mold parts to form a syringe connector shaped cavity;
• providing a material injection port in at least one of the plurality of mold parts;
• performing a single injection of material into the syringe connector shaped cavity to fill the syringe connector shaped cavity;
• and
• cooling the material to form the syringe connector.
