Abstract
A universal joint connected at one side thereof with a drive shaft having a pair of telescopic protective tubes extending thereover is protectively sealed by a protective boot which is joined with one end of the drive shaft. An annular bearing body formed on one of the telescopic protective tubes engages in an annular groove in a shank member of the universal joint and the protective boot includes a conical connecting portion extending over a connecting piece which is attached with one of the protective tubes. A securing ring is engaged in an outer groove of the connecting piece and a conical collar of the securing ring operates to press the conical connecting portion of the protective boot against a funnel-like extension of the connecting piece. The connecting piece is formed with through-holes which receive therein locking tongues formed on the annular bearing body and the securing ring includes a stop face which axially fixes the locking tongues in the through-holes.
