Abstract
The connecting element (1) is equipped in the region of a connecting portion (5) with a seal (7) which is fixedly connected with the housing (3) of the connecting element (1). Staying elements (9) protect the seal (7) against undue pressing forces. Between the housing (3) and one end of a corrugated pipe (2) a seal (12) is also disposed, which is nondetachably connected with the inner shell (14) of the housing (3) of the connecting element (1).
