Abstract: A container security clip comprises a U-shaped member adapted to be disposed over the edge of the side wall of an open-ended container. The U-shaped member includes first and second spaced leg portions. The leg portions each include first sharpened projections having a first and integrally formed with the leg and a second end extending vertically upward from the first end between the spaced legs. One of the leg portions includes a second projection integrally formed with the leg on one end and having a second end depending downward and outward from the first end. The first projections are adapted to engage the side wall of the container and embed therein to resist upward movement of the clip relative to the container; while the second projection is adapted to engage and embed in the container closure to resist movement of the closure and to rip the side of the closure if sufficient force is exerted to move it.
