Abstract: A concrete hose safety device has two stiff elongated hemi-cylindrical sections which may be half tubes or less than half, the sections having internal diameters roughly equal to the external diameter of a concrete hose. A plurality of hinge straps secure the sections in parallel and allowing them to open to allow a concrete hose to be laid therein and closed with the concrete hose secured therein. A plurality of closure straps then hold the device closed. In use, an operator may simply rely on-the device to prevent the concrete hose from whipping due to air in the hose, surge and so on.
