Abstract
A cooling channel cover for a piston of an internal combustion engine may include a body having mutually opposite end faces. At least one supply element for a coolant may be received in an opening disposed in the cooling channel cover. The supply element may include an inlet region and an outlet region, and may be held on the cooling channel cover via a clipped-in latching connection. A spring tab may be disposed on the inlet region of the supply element, and/or a latching element may be disposed on the outlet region of the supply element. The spring clip may engage one of the end faces and the latching element may engage the opposite end face.

A cooling channel cover for a piston of an internal combustion engine, comprising:
- a body having mutually opposite end faces and an opening;
- at least one supply element for cooling oil having an inlet region and an outlet region, the at least one supply element received in the opening and held on the body via a clipped-in latching connection;
- the at least one supply element, including at least one spring tab disposed at the inlet region extending radially outward in a circumferential direction of the body, at least one latching element disposed at the outlet region that is radially elastic in the circumferential direction of the body;
- and
- wherein the at least one spring tab bears against one end face of the mutually opposite end faces and the at least one latching element bears against the other end face of the mutually opposite end faces.
A piston for an internal combustion engine, comprising:
- a cooling channel cover having a first side and a second side disposed mutually opposite one another, and an opening extending transversely therethrough;
- at least one supply element for cooling oil having an inlet region and an outlet region, the at least one supply element received in the opening and held on the cooling channel cover via a clipped-in latching connection;
- the at least one supply element including at least one spring tab disposed at the inlet region extending radially outward in a circumferential direction of the cooling channel cover, and at least one latching element disposed at the outlet region that is radially elastic in the circumferential direction of the cooling channel cover;
- and
- wherein the at least one spring tab bears against the first end face and the at least one latching element bears against the second end face.
