Abstract
A method and a device for connecting a plastic line part in a plastic socket. A head end (9) of the line part (6) is heated contactlessly all the way round until the end curls over to a diameter that is greater than the inside diameter of the socket (5). The line part is then pushed into the socket without using a mandrel or insert, so that the head end (9) forms a liquid-tight fused connection of high tensile strength with molten wall material of the socket (5).
