An adapter device (100, 200) for use in combination with a syringe (20) to form an assembly (10) for delivering an intradermal injection. The adapter device comprises a body (110, 210) which is connectable to the syringe. A second nrimary skin contacting surface (232) is positioned at a distal end (126, 226) of the body. At least one support element (140, 150, 240) is con- nected to the body. With the assembly in an assembled condition, the at least one support element supports a needle cannula (24) connected to the syringe. The needle cannula is supported by the at least one support element intermediate a base (26) and a tip (28) of the needle cannula. At least a terminal portion of the needle cannula extends axially in a direction substantially parallel to at least a planar portion of the second primary skin contacting surface.
