A hydrokinetic coupling apparatus for a motor vehicle including a crankcase ( 12 ), designed to link in rotation, about an axis X, an input shaft to an impeller wheel; a turbine wheel ( 18 ) designed to be linked in rotation to an output shaft ( 16 ) via hub ( 14 ) and a flange ( 24 ) transversely oriented extending radially outwards relative to the hub; a lockup clutch ( 28 ) coupling the input and output ( 16 ) shafts comprising a piston ( 30 ) for releasably connecting the turbine wheel ( 18 ) to a substantially transverse wall ( 20 ) of the crankcase ( 12 ) against which the piston ( 30 ) is urged to lock the coupling; and at least a friction stop ( 68 ) interposed axially between the turbine wheel ( 18 ) and the piston ( 30 ). A friction stop ( 68 ) is arranged radially beyond the outer periphery ( 100 ) of the flange ( 24 ).
