Perforations in the baseboards for the fixing of a baluster on a support, in the case of concrete, in particular of a balustrade for guardrail, whose body comprises a housing in which the foot of the baluster can be fixed at an adjustable level by means of a locking member in the form of a wedge, provided with a thread for a screw that makes it possible to press this member between a face of the baluster and an oblique surface of the housing, as well as a sole having, on the one hand, two openings arranged to and another part of a plane of symmetry common to the housing and the sole, for the passage of screws, or analogous organs, intended for fixing the base in the support and, on the other hand, at a certain distance from these openings, means which define for the socket a tilting axis oriented transversely to the plane of symmetry, to allow an angular adjustment of the baluster under the action of a regulating screw-regulator located in the plane of symmetry on the side opposite the pivot axis, with respect to the openings, and resting on the support or on an element interposed between the base body and the support, characterized in that the adjusting screw (26) is threaded on the thread (27) of the locking wedge (17).
