Abstract: Plug connectors include a housing made of electrically insulating material; an outer conductor part, which is arranged inside the housing and is formed in a portion as a hollow cylinder or is formed entirely as a hollow cylinder; an inner conductor part, which is arranged at least partially inside the outer conductor part; and an insulating part, which is arranged at least partially inside the outer conductor part and at least partially encloses the inner conductor part. The outer conductor part in the interior of the hollow cylinder has exactly two opposing spines, each of which has a plateau offset inwards with respect to an inner wall of the hollow cylinder.

Abstract: A sanitary line connection is provided, which has a sleeve shape at least in a front-end region thereof and in which there is at least one sealing ring (7) clamped in a sealing way between the adjacent line section and the line connection. The line connection can be embodied, for example, as a sanitary outlet nozzle (1), with at least one retaining cam or similar retaining projection (9) projecting from the outer periphery of the sealing ring (7). The retaining projection (9) engages in an indentation or similar recess in the sleeve interior of the sleeve-shaped front-end region.
