<p>The invention relates to a stanchion. The inventive stanchion can be extended with the extraction of an inner tube which is disposed coaxially inside an outer base tube. Moreover, the invention is equipped with a safety device which prevents the aforementioned tubes from being separated fully from one another and which comprises tube connection means. According to the invention, the connection means prevent the separation of the tubes, while enabling the lower end of the inner tube to move between two fixed points, namely: a first point which is disposed inside the base tube and a second point which is determined by the length of the connection means. The connection means comprise a long, thin linking element, such as a rod, cable or similar, which is disposed longitudinally inside the base tube, such that one end thereof is fixed to the base tube and the opposing end is inserted into the inner tube, said opposing end being equipped with a stop block which prevents the extraction thereof from the inner tube.</p> |
