A clamp housing (11) for cylindrically wound heaters (12), particularly for an injection molding nozzle heater, has a slit (16) that permits changing the effective diameter of the housing (11) and it is actuated by an axially extending cam pin (40) that can be easily adjusted from an exposed end of the heater (12). The cam pin (40) has a central cam portion (42) formed between two end hubs (41) that axe rotatably mounted with respect to one edge of the longitudinal slit (16) in the clamp housing (11). The central cam portion (42) that is mounted in a loop (30) formed from the opposite edge of the slit (16) in the housing (11). As the cam pin (40) is rotated the two edges of the slit (16) in the housing (11) can be forced together because of the cam action and the housing (11) will tighten around a heater (12) held on the interior of the clamp. |
