1 Claim. (Cl. 15-119)
of an elliptically shaped ring having a slot or gap 13
opening through its bottom. The inner wall of the ring
at both sides of the gap is provided with a groove 14 for
the reception of a gap closure 15. One end of the gap
closure is offset and pivoted at 16 to the extractor at one
side of its gap. The upper face of the gap closure is
shown as curved to form when the gap closure is in closed
