Abstract
A locking device (6) for connecting a driveshaft (4) to a power take-off shaft (2) includes a coupling sleeve (7) mounted on the driveshaft in which locking members (12) are guided which lock the coupling sleeve against axial movement relative to the take-off shaft. A locking sleeve (14) is movable on the coupling sleeve (7) to lock the locking members (12) against movement or release them. A latch arrangement is provided to latch the locking sleeve in its release position during connection. The latch arrangement includes a stop (24) extending inwardly from the locking sleeve (14) and engageable with a stop (19) on the coupling sleeve (7) by tilting the locking sleeve on the coupling sleeve.
