by comprising a steel tube core (10) with inner tubes (11) for adjusting the distance
from floor and ceiling, and two metal end members (20) forming head and bottom of
tube (10) respectively. The outer free surface (24) and the periphery (23) of each
member (20) are provided with grooves (25,26) and associate first and second engagement
means (35,36) in an axial and transverse direction to the tube (10) are respectively
provided. Each engagement means (35,36) is adapted to be fixed to the other and to
