摘要： This invention concerns a plastic, buttonlike connector for securing a pair of crossed ropes together and also, a method and mold for forming the connector upon a pair of crossed ropes by injection molding operations. The method of injection molding of a plastic connector about a pair of crossed ropes involves steps of holding the rope in position within a mold cavity while a plastic is being injected into the mold cavity. The construction of the mold cavity includes features to so restrain the ropes and also includes passageways to permit a pair of ropes to extend from the cavity, but with the passageways being closed by the ropes to prevent loss of plastic during the injection operation.
