Improved telescopic manual locking device, in assemblies of the type involving a tube and an inner element, such as another tube or stem, characterized essentially by the fact of comprising a threaded bushing threaded onto a threaded pin at one end of the tube or inner stem and interposed between said end and a nut applied in the end area of said pin, the inner wall or the section of the outer tube being of substantially polygonal shape with which the nut practically corresponds, so that when manually causing the relative rotation of the outer tube with respect to the inner tube or stem, the sleeve is compressed by dilating radially and fitting into the essentially polygonal inner wall of the outer tube thus obtaining blocking between the outer tube and the inner tube or rod in a chosen position.
