Abstract: A window unit with a glazing panel, a frame with a profile that encompasses the glazing panel's edge, and grips the glazing panel on at least two peripheral sides as a ring; the frame has a primary part in the form of a hard component. The frame's primary part has at least one clip-like assembly that has top and bottom elements; the clip-like assembly clips and maintains the trim element's lug between the top and bottom elements. The top element is shifted from the bottom element along the edge. The clip-like assembly and the primary part are a single component. The top and bottom elements are flexible in a perpendicular direction to the axis of penetration of a trim element plugged into the clip-like assembly.
