The invention relates to a joint (1) for an orthopaedic device, which has a first articulated arm (2) and a second articulated arm (4), which are mounted about a swivel axis (6) in a swiveling manner relative to each other, and a blocking device, which can be moved to a release position and a blocking position, wherein the blocking device in the blocking position blocks the swiveling of the first articulated arm (2) relative to the second articulated arm (4) in the first swiveling direction, independently of a swivel angle between the first articulated arm (2) and the second articulated arm (4), insofar as said swiveling angle is in a predetermined range and allows the swiveling in the first swiveling direction, insofar as the swiveling angle is outside of the predetermined range.
