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.

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.

Abstract: The invention relates to a device for connecting lines, especially to a quick-connector, having at least two connections, with at least one connection thereof comprising two extensions to form a receiving portion for a line end, wherein one of said two extensions has a first section and a second section with a wall thickness larger than that of the first section. According to the invention a process optimization of the mounting processes is achieved by providing a transition with a wall on the side of the receiving portion between the two sections of the extension, which is curve-shaped in the longitudinal direction of the connecting device.

Abstract: The invention relates to moulded bodies which comprise evaporation-sputtered layers, and pipes or tubes which comprise these types of layers for increasing the barrier properties.

Abstract: The invention relates to a coupling unit for tubes o the like, comprising a coupling body with an opening for receiving therein a tube, and a latching device which is adapted to be transferred between: an unlatched position in which the tube is adapted to be moved relative to the coupling body, and a latched position in which the tube is adapted to be secured in the coupling body against removal therefrom. In order to improve the known latching systems for coupling units in the case of a crash or fire, the invention provides a coupling unit of the type referred to at the beginning, in which the latching device is magnetically operable for transfer between the unlatched position and the latched position and/or between the latched position and the unlatched position.
