The device (9a, 9b) has an activator cylindrically formed in a coupling half that rests opposite to a control piston (11), and including a circular nut (18) adjacent to a free end of the activator. Two locking balls (14) are engaged into the nut, when the piston is moved against force of an energy accumulator (12) lying in a coupling plug (10). The locking balls lie in a radial hole of the coupling plug, and are supported on a lateral surface (15) of the piston. The locking balls lie on a support edge (16) of a guide bushing (7), and lie outside of support region of the piston. |
