  Within the non-Abelian SU(2) Proca-Higgs theory, we study localised axially
symmetric solutions possessing a finite field energy. It is shown that in a
certain sense such solutions are analogues of the Nielsen-Olesen tube, since
they have a longitudinal magnetic field creating a flux of this field over the
central cross-section of the Proca tube. The main difference between the Proca
tube and the Nielsen-Olesen tube is that the Proca tube is described by a
topologically trivial solution and has finite size, since its energy density
decreases exponentially with distance. The dependence of the total field mass
of the Proca tube on the value of one of the parameters determining the
solution is examined in detail. The solutions are obtained both in the presence
and in the absence of external sources (charge and current densities).
