Abstract: A multi-line plug connector for connecting two heated fluid lines by way of a single connecting operation, including a female plug component which is connected with a male plug component. Each plug component includes a fluid connection and two electrical connections. Each plug component also includes an inner space in which a spectacle component is housed. The spectacle component has two guide channels for receiving electrical lines equipped with electrical contacts. The guide channels are connected with one another by a bridge that is fastened with a latching mechanism that secures the spectacle component against displacement along and/or obliquely to the coupling axis. The spectacle component receives a tubular fluid connector, connected with the spectacle component with form-fit and/or friction-fit, whereby the tubular fluid connector can be connected on one end to the heated fluid line and on the opposite end the fluid connector.

Abstract: A hose-line connector, with a connection part having at least one elongated hose connection for slipping a hose line onto the hose connection. The hose connection has a sealing segment having a circumferential sealing surface at a free front end and a retaining segment axially adjacent thereto as a clamping region for the circumferential radial clamping of a hose line. On the outer circumference of the retaining segment, the retaining segment has a radially protruding rib structure, which includes at least one circumferential rib in the form of an annular ridge and at least two longitudinal rib distributed about the circumference and extending axially or at an angle to the axial direction.

Abstract: The present disclosure relates to a hose-line connector, comprising a connection part having at least one elongated hose connection for slipping a hose line onto the at least one hose connection. The hose connection has a sealing segment having a circumferential sealing surface at a free front end and a retaining segment axially adjacent thereto as a clamping region for the circumferential radial clamping of a hose line that is slipped on. On the outer circumference of the retaining segment, the retaining segment has a radially protruding rib structure, which has at least one circumferential rib in the form of an annular ridge and/or at least one longitudinal rib distributed over the circumference and extending axially and/or at an angle to the axial direction.
