1. An adaptor for use with a drug delivery device having a reservoir for containing a product, said adaptor comprising:
a collar engageable with a distally projecting end-piece of said reservoir, said collar comprising an abutment surface on an inner wall of the collar, wherein said abutment surface is configured to limit translational movement of said collar with respect to said distally projecting end-piece once said collar is engaged with the distally projecting end-piece;
at least one adaptor anti-rotation member comprising a part located on said collar and capable of being engaged in a complementary part located on an outer wall of said distally projecting end-piece until a predetermined value of turning torque is applied to said collar, when said collar is engaged with said distally projecting end-piece; and
at least one deactivating member configured to neutralize said at least one adaptor anti-rotation member in response to a turning torque equal to or greater than a predetermined value applied to said collar when said collar is engaged with said distally projecting end-piece, thereby allowing the rotation of said collar with respect to said distally projecting end-piece.
