Abstract
A collet assembly for a hose crimping tool is disclosed in which rigid metal jaw elements are encircled by and locked within a separately molded elastomeric cage. The cage positions the elements in the free state and allows them to be radially compressed for the crimping operation. Interlocking surfaces are provided to retain the jaws within the cage without need of adhesives, or the like.
