A tubular charge holder assembly for a perforating gun made of a tube having a plurality of pairs of diametrically opposed openings. The pairs of openings are formed over a length of the tube, wherein the each pair has a larger and a smaller opening. A shaped charge is located within the pairs of openings in the tubular charge holder so that at least a portion of the rim of a front face of the shaped charge extends out of the larger opening and at least a portion of a rear face of the shaped charge extends out from the smaller opening of the tube. A detonating cord is helically wrapped around the outside surface of the tube such that the detonating cord is positioned so that the cord is proximate to the rear surface of each of the shaped charges installed within the tube. A substantially semi-circular clip is positioned on the outside surface of the tube proximate each of the shaped charges. Each clip includes first hook on a first end and a second hook on a second end on the front of the clip for engaging at least two portions of the rim surrounding the front face of the shaped charges. On a back of the clip, the clip has a retainer, such as a U-shaped portion or snap device to secure the detonating cord proximate to the rear surface of the shaped charge. The retainer may be perpendicular to a longitudinal axis of the clip or may be angled or offset with respect to the longitudinal axis of the clip to accommodate the helically wrapped detonating cord. The clip may be a wire, a pair of wires, a band, a perforated band having a adjuster or other suitable configurations.
