<p>A universal joint assembly connecting a pair of shaft ends is provided with a protective boot having a bellows-like configuration defining circumferential folds and including a conical connecting portion. A connecting piece is provided for joining a protective tube of one of the shafts with the protective boot. The connecting piece includes a funnel-like extension partially projecting into the conical connecting portion of the protective boot and a rigid supporting ring engages about the protective boot. The supporting ring includes a conical part adapted to extend in embracing engagement over the conical connecting portion of the protective boot, the conical part extending to partially overlap with a funnel-like extension of the connecting piece. The supporting ring is formed with a bead which is directed radially inwardly into engagement with one of the folds of the protective boot, the bead being formed on one side with a conical surface to facilitate insertion of the boot into the supporting ring and on the opposite side with a hook-like shape for maintaining engagement within the fold.</p> |
