Abstract
An adaptor intended to be mounted on a distal tip of a drug delivery device is provided. The distal tip defines an axial passageway for transfer of a product contained in the drug delivery device. The adaptor has a longitudinal axis A aligned on the axial passageway. The adaptor includes: a connection member for connecting the adaptor to a connector; an inner ring releasably engageable on the distal tip; and a compression component separate from the inner ring and configured to be unreleasably snap-fitted onto the inner ring engaged on the distal tip by proximal movement of the compression component with respect to the inner ring. The compression component is configured to exert a centripetal pressure on the inner ring so as to prevent axial movement of the inner ring with respect to the distal tip.
