1. A needleless access device assembly, comprising:
a needleless access device provided with a straight external thread, said straight external thread having a major diameter of constant value over the whole length of said straight external thread; and
an adaptor for connecting a drug delivery device to the needleless access device, the adaptor comprising:
a globally tubular body having a proximal region and a distal region, said proximal region being provided with an engagement element for mounting said adaptor on the drug delivery device, said distal region being provided on its inner wall with an internal thread cooperating with said external thread on a determined length of said internal thread, said internal thread having on a distal part of said length, said distal part having a first length, a first major diameter of constant value mating that of said straight external thread, wherein said internal thread has, on a proximal part of said first length, a second major diameter, where the second major diameter is strictly smaller than the first major diameter, the proximal part of the internal thread being configured for cooperating with the same straight external thread as the distal part of the internal thread, wherein said internal thread further comprises a tapered portion linking said proximal part to said distal part, said tapered portion having a second length and said tapered portion of the internal thread being configured for cooperating with the same external thread as the distal part and the proximal part of the internal thread.
