A connector for a fluid line defines therein a fluid duct and whose wall
has at least one signal conductor for the transmission of electrical
and/or optical signals. The connector comprises a plug socket for the
fluid line, a holding device for holding the fluid line in the mounted
condition thereof and at least one signal switch contact for producing a
connection with the at least one signal conductor. The at the plug socket
the fluid line is provided with a guide means for angularly aligned
arrangement of the fluid line, such guide means being able to be
introduced into the at least one fluid duct and in the case of such
introduction it slides along at least one angular encoding means arranged
in the at least one fluid duct so that the fluid duct is able to be
brought into a predetermined angular position prior to contact being made
between the at least one signal switch contact and the at least one signal
conductor.
