Abstract
Prop, extendable by means of the removal of an inner tube coaxially disposed in an outer base tube, equipped with a safety device which prevents the complete separation of both tubes and which comprises connection means between the tubes, which prevent their separation but allow the movement of the lower end of the inner tube between two fixed points, the first of which is disposed on the inside of the base tube, as the second point is determined by the length of said connection means, since the connection means are composed of a thin and elongated connection element, such as a rod, a cable or similar, disposed lengthways on the inside of the base tube, with one end attached thereto and with the opposite end inserted into the inner tube, equipped with a stop block which prevents its removal from the inner tube.
