A turbine engine wheel, in particular for a low pressure turbine, is provided. The wheel includes blades, each including an airfoil connected by a platform to a middle wall or tang extending radially and itself extended radially inwards by a root mounted in a slot of a disk, the platform and the tang defining two side cavities arranged on either side of the tang, which cavities are circumferentially open and are situated facing corresponding cavities in the directly adjacent blades, and sealing members being housed in the cavities adjacent to the blades. An annular sealing end plate is mounted on the upstream or downstream end of the disk, between the platforms and the disk, so as to face the slots and the roots of the blades, and includes a rotary coupling device for coupling with at least one of the sealing members.
