Abstract: Described herein is a packaging clip for releasably securing overlapping packaging panels to one another. The packaging clip includes a biasing element that helps restrain relative movement of the panels in a first configuration, and in a second configuration encourages their release and indicates such to a user. In an implementation, the biasing element is associated with a locking mechanism. The locking mechanism includes a rigid portion that is engageable with each overlapping panel for limiting their relative movement in the first configuration. The locking mechanism is turnable or otherwise manipulateable to release the first and second panels. The biasing element can exert a biasing force that encourages exit of the locking structure, allowing the locking structure to protrude from the panels and provide a visual indication of the released state.
