A housing cover arrangement of a hand-held power tool has a cover having a cover edge and a lateral surface delimited by the cover edge. At least one spring clip is provided that removably connects the cover to a part of the power tool. The at least one spring clip is disposed, when securing the cover to the part, on the lateral surface in the area of the cover edge and is oriented in a clamping direction that extends transversely to the cover edge. At least two supports are disposed along the cover edge and act in the clamping direction. The at least one spring clip is arranged between the at least two supports.

A piston for a two-cycle engine having a piston head and a piston wall in which are disposed wrist pin eyes. At least one undercut is formed between the underside of the piston head and the wrist pin eyes at a distance from the piston head. The undercut extends from the interior of the piston toward the piston wall. A respective thickened portion is provided in at least one region of the piston that is rotationally shifted about the longitudinal axis of the piston by 90&#xb0; relative to one of the wrist pin eyes. The thickened portion is disposed at a distance below the piston head and extends into the interior of the piston.
