7. The retail securing clip of claim 1, further comprising a mounting structure that extends from the clip body, the mounting structure is configured to support the retail securing clip.
8. A retail securing clip, comprising:
a clip head, the clip head includes a rotatable clip member and a clip base defining a cavity with a closed rounded end, the rotatable clip member rotates relative to the clip base about an axis of rotation, the rotatable clip member includes a locking tab having a rounded outer surface located proximal to the clip base at a flat surface of the clip base;
a clip body, the clip head is attached to the clip body at an interface of the clip head and the clip body;
wherein the rotatable clip member rotates about the axis of rotation between an open state and a closed state, in the open state a space is formed between the rotatable clip member and the clip base, wherein the locking tab projects into the cavity toward the closed rounded end in the closed state, and wherein a gripping ridge projects radially outward from the rounded outer surface of the locking tab such that the gripping ridge projects towards the closed rounded end of the cavity of the clip base; and
further comprising an over-center point and as the rotatable clip member rotates from the closed to the open state or from the open to the closed state it transitions through the over-center point, in the closed state the over-center point meets the clip base thereby creating a torque that causes the locking tab to place a force on the clip base.
9. The retail securing clip of claim 8, wherein the rotatable clip member includes a rotatable clip member base and the locking tab protrudes from the rotatable clip member base.
10. The retail securing clip of claim 9, wherein the rotatable clip member includes a curved inner surface that extends from the rotatable clip member base to a distal end of the rotatable clip member and has a radius of curvature of between 0.5 and 1.0 inch.
