A grease gun for supplying a lubrication nipple (45) with grease under pressure. The grease gun has a nozzle (12) with retaining elements (43) which, when the grease is being supplied to the lubrication nipple (45), are guided to engage therewith, and has two valves (13, 14) which can be opened alternately by means of an operating handle, of which the one (13) supplies the nozzle (12) with grease when it is opened while the other (14) connects the nozzle (12) to a grease receptacle (39) when it is opened in order in this way to relieve the pressure so that the nozzle (12) can be detached from the lubrication nipple (45). <IMAGE> |
