FLUIDIC CONNECTOR PLUG

The invention relates to a fluid connector (1) which serves to fluidly connect a tubular or hose-like line (29) to a connection (56). In particular, the connector (1) serves to establish a pneumatic connection in a compressed air system of a commercial vehicle. The connector (1) according to the invention comprises an inner part (5), an outer part (4), and a securing element (3), which is designed as a securing ring (2). The securing element (3) can be inserted (possibly also together with the outer part (4)) into the connection (56) with insertion forces which are on the order of magnitude smaller than the maximum securing force against removal from the connection (56). For this purpose, for example, a spring tongue (12) can be latched in an undercut (62) of the connection (56).
