A tubing break-off tool designed especially for adjusting the length of a thin walled tubular sleeve. The break-off tool includes an internal support for internally supporting the sleeve on one side of the plane along which it is to be severed, and an external support for externally supporting the sleeve on the same side of the severance plane as the internal support. The supports may be mounted in plier-type carriers to pivot the supports with respect to each other. A stepped plate member may be provided for use with the internal and external supports for externally supporting the sleeve opposite the internal and external supports for breaking the sleeve in the desired plane if the sleeve is pregrooved at the breaking plane. Alternatively, a severing member may be provided for use with the internal and external supports to sever the sleeve along the breaking plane.
