A double-ended sleeve for a tube fitting whereby the ends may be selectively interchangeable as a means for effecting a self-flare connection at the end of the tube to seal fluid pressure and as a means for effecting a collet-grip connection around the tube in advance of the self-flare connection to absorb tube vibrations. Both ends of the sleeve are of like construction and each end comprises a discontinuous annular body having at least slot means extending longitudinally thereof. Intermediate the two ends of the sleeve, is a continuous annular body portion having opposed clamping shoulders adapted for selectable engagement by the nut.
