A dispensing device 10 for dispensing compressed fluids from a can through a valve stem of such a can, the dispensing device 10 comprising: (a) a hollow tube 20 having opposing entrance 28 and dispensing 24 ends, the hollow tube 20 defining a channel 22 entirely through the tube 20 from the entrance end 28 to the dispensing end 24; (b) a connector 40 defining a conduit 46 there-through with one end of the conduit 46 mating with the channel 22 of the hollow tube 20 to provide fluid communication through the conduit 46 and channel 22 and where the opposing end of the conduit 46 is capable of attaching to a valve stem of a can; (c) a plug 30 located in and able to move within the channel 22 of the hollow tube 20, wherein the plug 30 and hollow tube 20 mate in a sealing configuration that seals the channel 22 from fluid flow when the plug 30 is pressed towards the dispensing end 24 of the hollow tube20; (d) a flexible and inelastic extension piece 50 having opposing first and second ends with the first end attached to the plug 30, the extension piece 50 extending through at least part of the channel 22 of the hollow tube 20 and optionally through at least part of the connector conduit 46; and (e) a sealed port 60 defined in the hollow tube 20, the connector 40 or both and through which the flexible and inelastic extension piece 50 extends from inside the channel 22 or conduit 46 to outside of the dispensing device 10; characterized in that the second end of the flexible and inelastic extension piece 50 is attachable to a can, and wherein the extension piece 50 is long enough so that when the connector is attached to the valve stem of such a can the plug 30 can be in a sealing configuration when the extension piece 50 is attached to the can but short enough so that when the connector 40 and valve stem are tilted away from the extension piece 50 with respect to the can the plug 30 is unable to be in its sealing configuration, and wherein the dispensing device 10 is free of a spring that presses the plug 30 into sealing configuration. (a) a hollow tube 20 having opposing entrance 28 and dispensing 24 ends, the hollow tube 20 defining a channel 22 entirely through the tube 20 from the entrance end 28 to the dispensing end 24; (b) a connector 40 defining a conduit 46 there-through with one end of the conduit 46 mating with the channel 22 of the hollow tube 20 to provide fluid communication through the conduit 46 and channel 22 and where the opposing end of the conduit 46 is capable of attaching to a valve stem of a can; (c) a plug 30 located in and able to move within the channel 22 of the hollow tube 20, wherein the plug 30 and hollow tube 20 mate in a sealing configuration that seals the channel 22 from fluid flow when the plug 30 is pressed towards the dispensing end 24 of the hollow tube20; (d) a flexible and inelastic extension piece 50 having opposing first and second ends with the first end attached to the plug 30, the extension piece 50 extending through at least part of the channel 22 of the hollow tube 20 and optionally through at least part of the connector conduit 46; and (e) a sealed port 60 defined in the hollow tube 20, the connector 40 or both and through which the flexible and inelastic extension piece 50 extends from inside the channel 22 or conduit 46 to outside of the dispensing device 10;
