Claims14
A cartridge type heater comprising:
- a jacket pipe comprising metal;
- an electric heating element arranged within said jacket pipe;
- and
- a terminal lug connected in one piece to said jacket pipe, said terminal lug being provided at one end of said jacket pipe, said terminal lug having at least one terminal lug section, said at least one terminal lug section being formed by an edge area section of an edge area of said jacket pipe, said at least one terminal lug section being separated from a first jacket pipe section of said jacket pipe and a second jacket pipe section of said jacket pipe by recesses, said recesses passing through a pipe wall of said jacket pipe, said first jacket pipe section being located adjacent to one of said recesses in a circumferential direction, said second jacket pipe section being located adjacent to another one of said recesses against the circumferential direction.
