A hot runner nozzle (10) with lateral electrode terminals (28) has a broad flanged body (18) that continues as a thermally graded narrower shaft (20) through which a heatable flow tube (22) extends. Into its high-strength foot portion (38), at least one nozzle tip (50, 50') is insertable; a high-strength heat-conductive envelope tube (30) having a re-entrant outer shoulder (34) adjacent the casing (12) is joined to a separating sleeve (36) of the shaft (20). The lower end of a heating tube (26) is thermo- conductively connected to a metal bush (40) whose upper portion is thermally insulated by air gaps (54, 44) from both the separating sleeve (36) and the heating tube (26). A supporting ring (56) of low heat conduction is mounted between axial faces of the heat-conductive bush (40) and the separating sleeve (36). The nozzle tips (50, 50') are form-fitted or welded to the foot portion (38) at an angle between 0° and 90° relative to the axis (A) of the shaft (20). The foot portion (38) is centered in a divided mold insert (16) wedge-fitted into the casing (12).
