Liquid line with a plastic corrugated hose

A liquid line for a cleaning apparatus in a vehicle, comprising:

• at least one corrugated hose and at least one connection piece configured to connect the liquid line to a further component,
• wherein the corrugated hose and the connection piece comprise plastic and are connected to one another via at least one welded connection;
• wherein the welded connection is produced by means of a laser welding process;
• wherein the welded connection is tight at least up to a defined operating pressure in the liquid line;
• wherein a stop is formed in the connection piece and defines an axial end position of the corrugated hose in the connection piece,
• wherein the stop has a profile which, in terms of its entire radial extent, is formed to be substantially entirely complementary to a corresponding end of the corrugated hose such that an axial contact surface between the corrugated hose and the connection piece extends over the entire radial extent of the corrugated hose wall at the corresponding end of the corrugated hose;
• and
• wherein the connection piece comprises a pipe portion which radially engages around outside of an end portion of the corrugated hose and a guide element which engages axially into the end portion of the corrugated hose, the guide element and the pipe portion forming a receiving space therebetween, the end portion of the corrugated hose being received into the receiving space and welded at its outside diameter to inside of the pipe portion.
