ABSTRACT:
A pipe holding collet is provided with an insert assembly that can be readily and quickly changed without the use of tools so as to adapt the collet to hold tubes of different sizes. The insert assembly is formed of a number of identical longitudinally separate segments, radially urged outwardly by compression springs and held together in a unitary assembly by a segment encircling retainer ring. The radially contractible and expandable assembly is releasably held within the bore of a master collet by means of an interengaging circumferential groove on the inner surfaces of the master collet fingers and circumferential ribs on the outer surfaces of the insert segments.
