Claim:
1. A line connector having two mutually separate flow paths for two fluid media, one flow path for a functional medium in the form of a urea-water solution in an SCR catalytic converter system of a motor vehicle, and another flow path for a temperature control medium for controlling the temperature of the functional medium, the line connector adapted to be connected to a double line which is composed of an inner line and an outer line substantially coaxially surrounding the inner line, the line connector comprising: a connector body having three line connections, a first connection for a first line which conducts the functional medium, a second connection for a second line which conducts the temperature control medium, and a third connection, in the form of a double connection for connecting with the double line, the third connection having an inner connecting element with an inner passage for communicating with the inner line and an outer connecting element with an outer passage for communicating with the outer line, and with the connector body being formed in its interior such that the first and second connections merge separately from one another into the inner and outer passages, respectively, of the third connection, the connector body being formed of two pieces including a connector housing and an insert piece cohesively connected together, the insert piece being circumferentially surrounded by the connector housing to define an annular chamber circumferentially around the insert piece into which the second connection opens, the inner connecting element having a first end defining a receptacle configured to receive the inner line within the inner connecting element, the inner line adapted to be cohesively connected to the inner connecting element; and said inner connecting element also including a second end which is plugged together with said insert piece, whereby said annular chamber being connected to the outer line by a plurality of ducts which forms said outer passage, whereby said plurality of ducts and said outer passage are constituent parts of said connector housing and the second end of the inner connecting element being formed in one piece with the connector housing in the region of said ducts and said outer passage.
