Connection device for telescopic bodies, essentially characterized by being constituted by an elastic bushing threaded by a threaded rod with coupling between them by an anti-rotation square, one of the bases of said bushing occupying the head of the said rod while the other is occupied by a washer anchored in the bushing itself, so that when the rod is threaded in a small bushing associated with one of the pipes to be joined, the widening of the elastic bushing is produced to press in firm connection against the internal walls of the external telescopic tube. Splice with it, being able to obtain bodies of great length by successive splicing of tubes of such type. (Machine-translation by Google Translate, not legally binding)
