A connector retains a medicine reservoir in a housing. The connector snaps onto the reservoir, the connector and reservoir are inserted into an aperture in the housing, and the connector snaps into the aperture in the housing. The connector may have a tubing and needle fixed in it to insert into the reservoir. The connector does not require a particular orientation when snapped into the housing and some embodiments may rotate freely. When snapped into the housing, the connector provides an auditory cue. For removal of the connector and reservoir, the exposed portion of the connector is compressed from the side. The configuration of the connector solves several problems associated with threaded connectors or other similar connectors.
