Abstract: A wire harness clip for securing D-scrolled wire harness to a panel type mounting surface, for example in an automobile. A clip has an elongated mounting arm with an open-faced D-shape trough formed at one end and a panel-mounting clip such as a Christmas tree clip formed at an opposite end, on a common surface or side of the mounting arm. The trough includes a hinged cover adapted to releasably lock a D-scrolled wire harness into the trough, and in the illustrated embodiment is a generally flat cover spaced from the and generally parallel to the mounting arm in the closed position, and includes a curved ratcheting lock arm which is automatically guided into locking engagement with mating ratchet teeth on an outer surface of the trough for closing the cover in a blind mounting operation. The trough preferably includes a pair of tape positioning tabs extending generally perpendicular to the mounting arm in alignment with the wire harness for pre-mounting the wire harness to the trough by taping.
