Abstract
A shaft coupling joining together a coupling sleeve and a power takeoff shaft, wherein a plurality of locking bodies guided in radial openings in the coupling sleeve engage within an annular groove in the power takeoff shaft to axially retain the members coupled together. An axially movable lock ring holds the locking bodies in engagement within the annular groove and when in the released position a gripping sleeve axially fixed with the lock ring, but rotatable relative thereto extending about the coupling sleeve, is engaged within the radial openings of the coupling sleeve to hold the coupling in the released position. The gripping sleeve is formed with an annular part extending axially inwardly of the gripping sleeve, a radially inwardly directed hooked projection provided on the annular part and a plurality of longitudinally extending slots uniformly circumferentially distributed on the annular part dividing it into a plurality of individual radially inwardly extending locking brackets having hooked projections formed thereon engaging within the radial openings. The quantity of the locking brackets provided is divisible by the quantity of the radial openings and the width of th…
