Abstract
A queue clip for mounting to a control gate includes a holder having a nose extending from one wall of the holder. A tongue is cantilevered off the nose and may be angled to either side of the nose. The tongue preferably supports a chain linking one crowd control gate to another. The tongue is inclined in an upward fashion to support downward chain forces. The tongue may also be angled to a particular side of the nose to allow the chain to be slid off the tongue such that a person may pass between the previously linked control gates.
