Abstract
An annular threading roll is releasably secured to one end of a support shaft by a ball detent which in its locking position seats at one side in a semi-spherically shaped recess that is formed in the inner peripheral surface of the roll, and which is engaged at its opposite side by an enlarged-diameter head formed on one end of an operating member that is mounted for limited axial movement in an axial bore in the shaft. The operating member is spring-loaded into a position in which its head engages the detent to keep the latter in its roll locking position, but the member can be pushed axially to a second position to remove its head from behind the detent which can then shift radially inwardly of the shaft to release the roll for axial movement off of the shaft.
