Abstract

A hot runner nozzle having an electrical heating element includes a connector for producing an electrical connection to a connection line, terminal contacts for the heating element terminating in an insulation body for the connector that separates the terminal contacts from one another electrically. The connection line has contact elements that are electrically contactable with the terminal contacts of the heating element. The insulation body is arranged at least in part in a receiving sleeve of the connector, that the connection line may be fixed in or on the receiving sleeve such that the contact elements of the connection line electrically contact the terminal contacts of the heating element, and that a first end of the receiving sleeve that faces towards the heating element wraps around the insulation body and has on this first end two opposing feet that face outward and that are attached to the heating element.
