A joint element (1) for a bearing structure, in particular for metal shelving, comprises a block (2) having two opposite coupling parts (3) each having an external lateral surface predisposed to joint-couple with a conical coupling with an internal surface of a tubular bearing upright (5). A central part of the block (2) comprises two lateral walls which are opposite and parallel one to another, between which a hollow space is defined, open on two opposite sides; the space is predisposed for joint-insertion, through each of the two openings on the sides, of an end of a support beam (7) of the bearing structure extended in a perpendicular direction to a longitudinal axis of the block (2). Each lateral wall exhibits two brackets (8) which project externalwise of the block (2) which are provided with holes for fastening an end of at least one auxiliary element of the bearing structure. <IMAGE>
