CONNECTING DEVICE FOR MEDIA-CONDUCTING, ELECTRICALLY HEATABLE PIPES

摘要

Disclosed is a connecting device for media-conducting, electrically heatable pipes. Said connecting device is designed as a plug-in connection in which at least one pipe end is fitted with a plug-in connector that can be plugged onto a mating plug-in connector piece mounted on a motor vehicle unit. The electrically heatable pipe comprises an embedded electrical heating conductor, the ends of which are brought out of the pipe in order to be assembled with a plug. The plug-in connector (6; 26) at the pipe end has a cylindrical housing section (8) onto which a cylindrical heating conductor fixture (7) can be slid, the surface of said heating conductor fixture (7) being provided with a helical groove (11). The heating conductor is inserted into the helical groove (11) in a spiraling manner in such a way as to cover the cylindrical housing section (8) in a spiral-shaped fashion.
