A vial access device, includes a body having a projecting annular skirt that is elastically deformable, for engaging a complementary shaped neck of a vial. A tubular spike extends coaxially within the annular skirt for introducing into the vial, and a tubular connector protrudes from the body on the side opposite to the annular skirt and in fluid communication with the tubular spike. The tubular spike and the annular skirt are arranged, respectively, within a first and a second part, distinct from each other, and of which the first part is permanently joined to the body and the second part is connectable to the first part through an irreversible coupling. |

1. A vial access device, comprising:
a body having a projecting annular skirt that is elastically deformable, for engaging the a complementary shaped neck of a vial, a tubular spike extending coaxially within said annular skirt for introducing into the vial, a tubular connector protruding from the body on the side opposite to said annular skirt and in fluid communication with said tubular spike, and the tubular spike and the annular skirt arranged, respectively, within a first and a second part, distinct from each other, and of which the first part bearing the tubular spike is permanently joined to said body and the second part bearing said annular skirt is connectable to the first part through an irreversible coupling, and wherein the first part comprises a generally circular disc from which said tubular spike centrally projects, around which a crown of hollow axial projections is arranged, and the second part is formed with a crown of corresponding axial bores, within which said hollow axial projections are engaged and blocked by means of plastic deformation. |
