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.

Abstract: A simulated weapon creates a muzzle flash and smoke effect. The simulated weapon has an elongated tube portion having a closed end and an open end. A high-intensity light source enters the elongated tube near the closed end. A communication passageway in the elongated tube conducts a pulse of theatrical haze through the weapon. A target illuminator is mounted on the elongated tube. A pressurized pulse of theatrical haze is delivered through a barrel of the weapon. The high-intensity light source is flashed as the pressurized pulse of theatrical haze exits the barrel.
