Abstract: A sleeve for surrounding a power cord, in whole or in part, for apparatuses such as hedge trimmers. The sleeve, preferably composed of a lightweight polymeric material in expanded, corrugated or similar form, has relatively large radial dimensions compared to the cord and therefore resists the insertion of the sleeve and the cord into apparatuses (such as a hedge trimmer's cutting blades) thereby preventing damage to the sleeve and the cord and preventing other undesired results. In addition, the relatively large size of the sleeve tends to increase the user's awareness of the sleeve and cord. Also the sleeve's increased rigidity compared to the cord aids in preventing the cord from being entangled in the apparatus and assists in managing and manipulating the cord. The sleeve is also lightweight and flexible enough so as not to constrain the intended function of the cord.
