Abstract

A protection arrangement for a joint (1), especially a double universal joint driving or in drives of agricultural devices and self-propelled implements, has a tube-like first protection element (12) with a first axial end (13) and a second axial end. At least the first axial end (13) is open. An attachment portion (16) is on the first axial end (13). The first protection element (12) is supported on a first component (4) of the joint (1). A second plastic protection element (17) is formed as a hollow body. The second protection element is open at both ends with an axially open first end portion (18) and an axially open second end portion (19). An envelope portion (20, 120, 220) is formed between the first and second open end portions (18,19). The envelope portion (20, 120, 220) has a lattice structure. The first end portion (18) is connectable to the attachment portion (16) of the first protection element (12). The second end portion (19) connects to a connecting element (7), which is supported on a second component (6) of the joint (1).
