Nozzle heated by means of electric heating cartridges for injection-moulding machines, having a nozzle body which contains the runner for the plastic, is held in a head plate fixed to the frame and is provided with blind holes which run essentially parallel to the runner for the plastic and are for receiving heating cartridges which are connected by means of armoured electrical lines to an external voltage source, in which arrangement the nozzle body is of a stepped design at its upper edge for the purpose of forming an annular shoulder and is provided with a covering cap, which forms with the annular shoulder an outwardly open annular space. The annular shoulder is of a stepped design in the nozzle body such that a passage extending underneath the rim of the covering cap from the annular space to a cable duct situated in the head plate is formed. <IMAGE>
