A support for human joints is disclosed having first and second rods which are connected to each other via articulation means which permits reciprocal rotation of the two rods about a rotation pin. The support includes locking means having a flexible cable which limits rotation between the two rods in an angular direction. The support has first fixing means for fixing a first end of the cable to the first rod or to the articulation means, and second fixing means for fixing a second end of the cable to the second rod or to the articulation means. The first fixing means also has a plurality of hooks. The first end of the flexible cable forms a loop suitable to engage selectively with one of the hooks to vary the anchorage position of the first end of the cable with respect to the first rod.
