The purpose of the present invention is to provide an articulating joint for limb braces such that adjustment of the range of movement can be facilitated and load can be reduced. The articulating joint is provided with: a first articulating joint part (2) having a horseshoe-shaped recess (8) with a rotation shaft (9) disposed substantially in the center thereof and a groove (13) which is formed in communication with the recess (8) at a position facing the substantially center part of the inner circumference (12) of the recess (8) a second articulating joint part (3) which has a first projection (20) formed so as to be insertable into the recess (8) and a second projection (21) spaced apart from the first projection (20) by a predetermined distance and formed so as to be insertable into the recess (8), said second articulating joint part (3) being mounted pivotally about the rotation shaft (9) and a torsion spring (16) which is rotatably placed over the rotation shaft (9) and has one end (18) bent in the centrifugal direction so as to be locked in the groove (13), with the other end (19) being bent in the centrifugal direction so as to be located between the first projection (20) and the second projection (21)Lobjectif de la présente invention est de fournir un joint darticulation destiné à des entretoises de membre et conçu de telle sorte que le réglage de la plage de mouvement peut être facilité et la charge peut être réduite. Le joint darticulation est pourvu : dune première partie de joint darticulation (2) présentant un évidement en forme de fer à cheval (8) avec un arbre de rotation (9) disposé sensiblement dans le centre de celui-ci et une rainure (13) qui est formée en communication avec lévidement (8) au niveau dune position faisant face à la partie sensiblement centrale de la circonférence intérieure (12) de lévidement (8) dune seconde partie de joint darticulation (3) qui présente une première saillie (20) formée de manière à pouvoir être insérée dans lévi
