<； p >； The Invention refers to a set of connection to a medicinal Liquid,That includes a Connector through which you can administer a medicinal Liquid； a fijaci u00d3n u00a0 piece which can connect the Connector and can be set to a Device Management PTo administer a medicinal Liquid through the Connector； and has an opening in which the Connector is coupled with the fixing piece and the ConnectorAnd a Sealing element to Seal the passage between the Connector and the fixing Piece, u00a0,Where the Sealing element can be inserted into the opening of the fixing piece in a direction of insertion so that the Sealing element is maintained between the fixing piece and theWhen the workpiece fixing Connector is attached to the Connector.The Sealing element has a Sealing Head, which closes the opening of the piece against the passage of liquid fixing piece is connected to the Connector, and a body.That joins the Sealing head which can be arranged in the opening with a radial distance to the fixing Piece.An interior Space of the Sealing element is free of any body having a support Point for the opening of the Sealing Head.It is expected that the Sealing element in the transition between the Sealing Head and BodyIt has a protrusion that protrudes radially with respect to the direction of insertion through the Sealing head which can contact a surface contact assigned along dAnd the direction of insertion into the opening of the fixing Piece, and a Flange that, with respect to the body of the Sealing element.Projected radially Outward along the direction of insertion of the outgoingThe fixing piece and the Connector is coupled between the fixing piece and the Connector so that the Flange rests with its underside on a contact surface of the Connector and its CHigher ara is at least partially exposed and is coupled to a Lower section through a fixing Piece attached to the Connector in a Recess in the associated Connector.This Way, you can create a connection to a set of medici
