The device makes it possible to measure the wear of a ball-and-socket joint (2) comprising a first ring (4), which delimits a spherical housing, a second spherical ring (6), which is positioned concentrically in the housing of the first ring, and a lining (8), which is made from an elastically insulating material and is inserted between the second ring and the spherical housing of the first ring, at least two electrodes (42, 62) provided to be connected to the first ring (4) and the second ring (6), respectively, or to the lining (8), so as to form a capacitor structure (C) and means (12-22) for measuring the capacity of the capacitor thus formed. The device further comprises an electronic circuit (22), which is a resonant circuit including the capacitor (C), an inductance (L) and a resistance (R) positioned in series.
