Abstract: A fastening device for a hand-held applicator of foam cylinders enables the use of foam cylinders with hand applicators that were intended for applicator guns. A fastening device for a hand-held applicator is used, which is placed on the valve nozzle of a foam cylinder. The fastening device has a cavity on the side of the nozzle, in which there is a conical pipe. In addition grappling devices, such as cammed surfaces, on the inside wall of the cavity of the fastening device engage a border of the nozzle.

Abstract: The present invention relates to the structure of a fastening device for a hand-held applicator of foam cylinders, in particular polyurethane foam cylinders used in construction that would enable the use of foam cylinders meant for applicator guns with hand-held applicators as well. For this purpose a fastening device (9, 19) for a hand-held applicator is used, which is placed on the valve nozzle (3). The fastening device (9, 19) has a cavity (12, 24) on the side of the nozzle, in which there is a conical pipe (13, 25). In addition, there are grappling devices (14, 26, 27) on the inside wall of the cavity of the fastening device, joggles for example, that are hooked behind the border (8) of the nozzle (3).
