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