The hydrokinetic coupling device (1) includes a housing (2) provided with a transverse wall, an impeller wheel (10), a central thrust ring (336), a locking clutch (4) with a piston (21) mounted so that it can move axially along the thrust ring (336). The piston (21) has pressings (111) directed towards the transverse wall (6) of the housing (2), while a connecting piece (522) connected to the wall (6) includes, at its internal periphery, complementary tabs (fingers) (523) able to come into engagement with the lateral edges (115) of the pressings (111).
