摘要

The sleeve (1) has a ring-shaped tubular sleeve body provided with a ring that is arranged around a collar body. The collar body surrounds a recessed part (4) with weakened material cross section, where the weakened material is compressed along longitudinal direction (2). The recessed part allows projection of a sealing ring into a transit channel of the sleeve body. Disk-shaped stiffeners (3) are separated from the recessed part and connected with each other along longitudinal direction. Circulating reinforcing ribs are formed in region of bending units.
