  • Publication number: 20060254897
    Abstract: A housing cover arrangement of a portable handheld work apparatus includes a releasable cover (1) and at least one spring clamp (2) for attaching the cover (1). The spring clamp (2) is pivotally held at one end (3) so it cannot separate and has an elastic latching spring lug (5) at its opposite-lying end (4). The spring clamp (2) is bent over to an approximately U-shaped section (6) at its pivot end (3). An open end (7) of the U-shaped section (6) is closed by an elastic plastic latch (8) while forming a pivot receptacle (9) for a pivot lug (10). The pivot receptacle (9) is essentially closed.
