摘要： A hot runner nozzle (1) for injection-molding forms has a nozzle body (2) with a throughput channel (3) connected to a nozzle exit (5) for melts. At least one jacket-heating unit (8) is located at the exterior perimeter of the nozzle body (2). This heating unit is enclosed at its exterior perimeter by a sleeve (10), which is flexible in the radial direction. The sleeve (10) is enclosed at its exterior perimeter by at least one circular lock (11) that rotates about its longitudinal axis (12) relative to the sleeve (10) between a released position and a clamped position. The facing surfaces of the sleeve (10) and the lock (11) each have a profile that deviates from that of a cylindrical shell located concentric to the longitudinal axis (12). The facing surface of at least one of these parts (10, 11) is at least in certain areas designed as awedge lock surface (13) that has an abutting slant located in a plane orthogonal to the longitudinal axis (12), against which a seating area of the surface of the other part (11, 10) lies (FIG. 1).
