A cable bundling system is disclosed. The cable bundling system includes a base having an opening extending through the base; a barb supported by the base and extending at least partially across the opening; and a strap adapted to be advanced through the opening in a first direction. When the strap is displaced in a second direction opposite the first direction, the barb pierces a medial portion of the strap such that the barb contacts the base. The strap can include a longitudinal groove extending a length of the strap, and the barb has a piercing portion opposite a supported portion. The piercing portion can pierce the medial portion of the strap.
