A joint for articulations with pseudo-elastic elements comprising a pair of coupled box-shaped elements (13, 14), facing each other in an open surface, moveable and rotating with respect to each other, around a common longitudinal axis (15) and containing a spring-charged pseudo-elastic element (12) which causes the reciprocal rotation, the box-shaped elements (13, 14) carrying an arm (20, 25) facing outwardly for connection with associated portions of an articulation and including stop elements (21, 32 132, 20) of their rotation. The spring-charged pseudo-elastic element (12) comprises a curved portion, more or less closed to form a ring (36) and two straight portions (37) terminating in ends (23, 34), inserted into holes (22, 33) of the box-shaped elements (13, 14), the straight portions (37) being intersected to obtain a pre-charge before being inserted into the holes (22, 33).
