A claw clutch for positively connecting a first rotatable component to a second rotatable component. A claw clutch for motor vehicles having an electric drive train which permits a reliable connection of the claw clutch when tooth-on-tooth positions are released and, at the same time, reduces the number of moving elements on the sliding sleeve. A clutch body, which is arranged on the first rotatable component for conjoint rotation therewith, has a first tooth system and a sliding sleeve, which is arranged on the second rotatable component in a manner which allows conjoint rotation and axial movement, has a second tooth system and is axially movable via a shift fork by an actuator system in order to load a spring element by the actuator system in the case of a tooth-on-tooth position. The spring element to be loaded is arranged outside the second rotatable component equipped with the sliding sleeve.
