Abstract: A hose clamp utilizing two constricting band type hose clamps which are tied together by means of a strapping arrangement includes one clamp which surrounds the hose itself and is provided with protuberances which press into the outer surface of the hose to provide a strong gripping function which prevents the hose from moving with respect to this clamp while at the same time engaging the hose in a non-destructive manner. The hose if not grippingly interengaged with the clamp would under pressure slide out of the clamp and off of the fitting. A second hose clamp is clamped about the rigid fitting to which the hose is attached at a point beyond an enlargement in the fitting, so that this clamp cannot move past the fitting enlargement. The straps connecting the two clamps then prevent the hose from sliding off of the rigid fitting because of the restraint provided by the clamp which is secured beyond the fitting enlargement.
