Improved extendable device, of the type comprising a central tubular body, with respect to which are telescopically displaced two opposite tubes, characterized in that said central tubular body, has axially coupled a rod endowed with extreme pulleys. Which penetrates the opposite telescopic tubes, the latter being related to each other by their conventional connection to a cable laid in a closed circuit between said pulleys so that the displacement transmitted to one of the end tubes, results in an antagonistic displacement of the other, under the movement of the link cable on the pulleys established on the rod of the device.
