3. An adaptor for connecting a drug delivery device to a connector provided with an external thread, the adaptor comprising a globally tubular body having a proximal region and a distal region, the proximal region including an engagement element for mounting the adaptor onto the drug delivery device, the distal region including an inner wall with an internal thread configured to cooperate with the external thread so as to connect the connector to the adaptor, the internal thread defining an internal thread crest, wherein the internal thread crest is provided with at least one deformable radial end part configured to be radially deformed when the connector is screwed into the adaptor, and wherein the at least one deformable radial end part comprises two projections that are both integrally provided directly on the internal thread crest in a diametrically opposed way with respect to a diameter defined by the internal thread crest, wherein the two projections are located on only the internal thread crest.
