Abstract

An injection molding nozzle with a hollow inner portion and a separate removable outer collar portion which sits on a seat in the mold. The outer collar portion has two separate semicircular segments which extend around and interlock with the inner portion with sufficient strength to prevent longitudinal movement of the inner portion when sealing pressure is applied. A resilient split retaining ring clamps the two semicircular segments together in the interlocking position. In one embodiment, the nozzle has an integral electrical heating element with lead portions which extend radially outward to a ceramic insulator. The ceramic insulator has an inner end portion which is also secured in place in an opening between the two semicircular segments.
