An annular cooling channel cover for a piston may include an elastic material body having opposing end faces. At least two opposing end regions may provide a joint gap and at least one feed element for a coolant may be received in at least one opening disposed in the cooling channel cover. The feed element may include an inlet region and an outlet region, and may be held on the cooling channel cover via a clip-on latching connection. Spring clips may be disposed on the inlet region of the feed element, and/or latching elements may be disposed on the outlet region of the feed element. The spring clips may engage one of the end faces and the latching elements may engage the opposing end face. A closure element may engage into the joint gap to close the same.
