The device D comprises elastic locking means B between a first element 1 and a second element 2 in the shape of a rod. The locking means B comprise a torsion spring 3 forming at least one loop intended to clamp the second element 2 in the shape of a rod, the ends of the torsion spring 3 being equipped with means M suitable for being grasped and for causing, by pinching, an unrolling of the spring 3 in order to allow the two elements 1, 2 to slide with respect to one another, the releasing of the ends of the spring 3 causing, again, the clamping of the element 2 in the shape of a rod and the locking of the two elements 1, 2 with respect to one another.
