A two part clip suitable for mounting to a holster, pouch, bag, or sheath and selectively clamping to a material, the clip comprising:

• a relative lower unit having a mounting area for said holster, pouch, bag or sheath, a base plate, a terminal clamping head comprising a gripping area and configured to receive a material, and a pair of opposing overhead flap mounting posts located at the top of the lower unit adjacent to the clamping head;
• and
• a flap having terminal mounting means pivotally attached to the relative lower unit via the mounting openings and configured such that application of a downward pressure on the external surface of the flap rotates the flap toward the base plate of the lower unit and engages and moves the clamping head into a closed position against the base plate and reducing the angle between flap and base plate to maintain position of a material received therein.
