摘要： A welding sleeve has a heating element (5) which consists of a resistance wire (6) mounted on a winding support (3). The ends of the resistance wire are inserted in slits of the retaining elements formed on the winding support (3), such that when plugged into a recess in the retaining element (10) a plug contact (15) slides onto the inserted resistance wire (6). The slit in the plug contact (15) simultaneously cuts into and clamps the resistance wire (6), thus producing a solid contact between resistance wire (6) and contact plug (15).
