A suction nozzle holster is provided with a latch mechanism for receiving a universally adjustable strap having a groove system whose individual grooves can engage with a pawl of a lever arm of said latch mechanism. A forward surface of the holster may be provided with a hole into which a suction hose can be forced in order to constrict said hose and, hence, curtail the vacuum conditions in a suction nozzle serviced by that hose.
