Abstract
A clamping device for two telescopic tubes (1, 2) comprises a ring (7) which is longitudinally split and thus defines a longitudinal spacing (8) located in a plane intersecting the ring (7) longitudinally, said ring (7) being extended towards the outside by two wings (9, 11) facing each other on either side of the longitudinal spacing (8), at least one rod forming an axis (A) arranged transversely in relation to the plane and passing through the two wings (9, 11), and an arm (12) which is fixed and pivots in relation to the rod forming an axis (A), so as to make possible clamping of the ring (7) by reduction of the longitudinal spacing (8), the two wings (9, 11) being brought towards one another.The arm (12) is divided into two branches (13, 14) each having a free end through which the rod forming an axis (A) passes, the two branches (13, 14) and also the free ends coming to lie on either side of the two wings (9, 11) of the ring (7) in order to enclose said two wings (9, 11).
