In the case of an injection nozzle, in particular hot-runner nozzle (7), for arrangement in an injection mould (11) which has a relatively large number of plates as a function of the configuration, and which has, on its solid mould side (I), at least one platen (4) and one feed plate (5), and, on its moveable, separable mould side (II) at least one cavity plate (2), at the mould cavity (3) of which a nozzle point (8) is used, where the hot-runner nozzle (7) has, at its rear end distant from the nozzle point (8), a hollow flange housing (18) which has a housing collar (11) and which receives a material tube (20) with a flow channel (9) for a material melt leading to the nozzle point (8), and also has connections for a heating system (16) and/or cooling system and temperature sensor (17), the material pipe (20) has been connected at its rear end by way of a delimited length section (21) of its outer jacket area to the flange housing (18) at the inner jacket area thereof so as to form a single piece.
