A compressed-air-operated differential lock of a motor vehicle, which is arranged within a metallic rear-axle transmission housing part having a recess. A piston is arranged displaceably in the recess in relation to its longitudinal axis and so as to be capable of being supported on a first claw clutch half which is arranged fixedly in terms of rotation in relation to a shaft and so as to be capable of being coupled to a corresponding second clutch half. In order to provide a cost-effective differential lock, a plastic liner is inserted into the recess and receives the piston so as to guide the latter along said longitudinal axis and in which an elastomeric sealing ring is snapped in a way beneficial in mounting terms and seals off relative to the compressed-air interior.
