To provide an improved adaptor for connecting a drug delivery device to a needleless access device.SOLUTION: The invention relates to an adaptor (1) for connecting a drug delivery device (100) to a needleless access device (200) having a straight external thread, the adaptor comprising engagement means for mounting the adaptor on the drug delivery device, and an internal thread intended to cooperate with the external thread (201) on a determined length L, the internal thread being the adaptor (1) showing on a distal part (5b) of the length L a major diameter D1 mating that of the straight external thread, characterized in that the internal thread shows on a proximal part (5a) of the length L a major diameter D2, where D2 is strictly smaller than D1, the internal thread further comprising a tapered portion (5c) linking the proximal part (5a) to the distal part (5b). The invention further relates to a drug delivery device comprising such an adaptor and to methods for connecting the needleless access device to the adaptor, and to the drug delivery device.SELECTED DRAWING: Figure 1 【課題】薬物送達デバイスを無針アクセスデバイスに接続するための改良型のアダプタの提供。【解決手段】本発明は、薬物送達デバイス（１００）を、直線状外ねじを有する無針アクセスデバイス（２００）に接続するためのアダプタ（１）において、アダプタを薬物送達デバイス上に装着する係合手段と、所定の長さＬ上で外ねじ（２０１）と協働するように意図された内ねじとを備え、内ねじは、長さＬの遠位部（５ｂ）上で、直線状外ねじの大径と噛み合う大径Ｄ１を示すアダプタ（１）であって、内ねじは、長さＬの近位部（５ａ）上に大径Ｄ２を示し、Ｄ２はＤ１よりも厳密に小さく、内ねじは、近位部（５ａ）を遠位部（５ｂ）に連結するテーパ付き部分（５ｃ）をさらに備えることを特徴とするアダプタ（１）に関する。本発明は、そのようなアダプタを備える薬物送達デバイス、無針アクセスデバイスをアダプタに接続する方法、および薬物送達デバイスにさらに関する。【選択図】図１
