  • CONNECTING APPARATUS COMPRISING A RETENTION COLLAR
    Publication number: 20180038531
    Abstract: The present disclosure relates to a connecting apparatus for connecting fluid-conducting lines comprising a first fluid-conducting line having a first connecting section, a second fluid-conducting line having a second connecting section, and a retention collar for fixing the connecting sections together. The second connecting section can be introduced axially into the first connecting section to provide a fluidic connection between the first and second fluid-conducting line. The retention collar has first retaining projections designed to engage into a first locking contour on the outer surface of the first fluid-conducting line. The retention collar has second retaining projections designed to engage into a second locking contour on the outer surface of the second fluid-conducting line. The first retaining projections engage into the first locking contour.

  • Device, arrangement and method for connecting lines, motor vehicle including such a device or arrangement, respectively
    Patent number: 9346215
    Abstract: The invention relates to an device for connecting lines, especially to a quick connector, comprising at least one connector adapted to be joined with a line end by means of friction welding. A controlled release of excess melt is achieved by that the connecting device is provided with means for withdrawing the melt producible by the friction welding from the its area of the origin.

  • Method and device for connecting pipes; motor vehicle with a device of this type
    Patent number: 8561875
    Abstract: The invention relates to a method for shaping pipes with the steps connecting a pipe end with a coupling of a connection device for pipes, in particular a quick connector, through friction welding and controlling the region of formation of the molten mass formed during friction welding. The contamination of the inside of the pipe due to welding beads can be prevented with the aid of the invention.
