An electrical heating element for heating liquid media, e.g. water, for use in water heaters or the like and particularly in the form of a heating cartridge, comprising an insulated housing which is constructed in two parts of which a sleeve-like outer part receives in drawer-like manner an inner part, a duct system formed in the inner part comprising uninsulated heating coils for heating the medium flowing over them, and form-locked sealing means between the inner and outer part shaped onto these parts to avoid any direct passage of the medium to be heated from an inlet within the housing to a outlet, the form-locked sealing means being particularly in the form of groove and tongue joints.
