An articulated coupling joint ( 1 ) for rail vehicles comprises a first coupling part ( 2 ) which has an outer surface ( 4 ) which is curved in the form of a spherical surface and forms a first contact face ( 5 ), and comprises a second coupling part ( 3 ) which has an inner surface ( 7 ) corresponding to the outer surface ( 4 ) and forming a second contact face ( 6 ) and has a holding ring ( 10 ) which is suitable for producing a welded connection to a connecting structure, the coupling parts ( 2, 3 ) being pivotable relative to one another, and a sealing ring ( 8, 8 ') which contacts both coupling parts ( 2, 3 ) being provided for protecting the contact faces ( 5, 6 ) of the coupling parts ( 2, 3 ).
