I said "limbs", but it might also be some "bead" (olive), "barrel" (especially the
open variation could be
fine to make barrel shape... just that open then would be a misname, unless we drop
the sphere forever and
open behave like "cone")... and some native English speakers are welcome to contribute

what it might looks like (without the spheres at the ends, and not pierced):
