Cable routing device

A cable routing device for installation on a post of a computing system board, includes a tube shaped main body having a hollow inner cavity. The main body includes a lower generally cylindrical portion having a first inner diameter sized to achieve a clearance fit over the post, and a flexible upper portion having a general shape of a truncated cone when in an unflexed condition, the flexible upper portion having slits arranged approximately opposite to each other thereby defining two sides to the flexible upper portion, the flexible upper portion having a second inner diameter proximate to a top of the flexible upper portion. When the flexible upper portion is in the unflexed condition, the second inner diameter is smaller than the first inner diameter and smaller than an effective diameter of the post, and when the two sides are flexed in an outward direction the device achieves a clearance fit over the post. The device further includes a cable clip molded to the main body, and configured to retain a plurality of cables.
