A protection arrangement for a double universal joint ( 1 ) for drives of agricultural implements has a first protection element ( 11 ), an annular second protection element ( 15 ) and a third protection element ( 18 ). The first protection element ( 11 ) has first holding projections ( 14 ) circumferentially distributed on its outer circumference ( 13 ) close to the first front edge. The first holding projections ( 14 ) project beyond the outer circumference ( 13 ) and form at least over a circumferential edge portion, distanced to the first front edge, a groove. A support tab projects beyond the first front edge. The second protection element ( 15 ) has second holding projections ( 17 ) circumferentially distributed on its outer circumference close to the second front edge. The second holding projections ( 17 ) project beyond the outer circumference and form, at least over a first circumferential edge area close to the second front edge, a second groove. An undercut portion is formed over a second circumferential edge area distanced to the second front edge. The third protection element ( 18 ) has holding portions at both ends. The holding portions include a number of first through holes ( 20 ) or second through holes, respectively. The through holes engage the holding projections ( 14, 17 ), corresponding in number to the first holding projections ( 14 ) and second holding projections ( 17 ).
