1. An adaptor for connecting a drug delivery device to a connector, the adaptor comprising a tubular body, said tubular body having a proximal region and a distal region comprising an internal thread, the proximal region being configured to engage a distal tip of said drug delivery device and the distal region being configured to be connected to the connector, said distal region having a distal end delimiting a distal opening so as to permit introduction of the connector inside the distal region of the tubular body,
wherein the distal end of said distal region is configured to be clamped to the connector when said connector is introduced inside the tubular body,
wherein the adaptor further comprises at least one deformable element having a base portion connected to the distal end of said distal region and a free end comprising an upper side wall and a lower side wall extending radially inward from the base portion,
wherein, in a rest position in which the connector is away from the adaptor, the free end of the at least one deformable element extends distally from the base portion, such that the upper side wall and the lower side wall of the free end are distally angled at an angle relative to a plane substantially parallel to the distal opening of the tubular body, and
wherein said free end is configured to bend towards the proximal region when the connector is introduced inside the tubular body, such that the upper side wall and the lower side wall of the free end are proximally angled at an angle relative to the plane substantially parallel to the distal opening of the tubular body, and such that the free end of the at least one deformable element is configured to sag and rub against the internal thread of the distal region providing a ratchet limiting removal of the connector from the adaptor.
