ABSTRACT:
Apparatus for securing a fragile cylindrical tube within an envelope by using at least two spaced-apart mounting rings which tend to center the tube within the envelope. Each mounting ring is provided with three radially-extending through-holes, and an elastic sphere having a diameter greater than the thickness of the ring placed in each through-hole is in contact with the inner surface of the envelope and the outer surface of the tube, thus centering the tube within the envelope.
