An entry fitting having a cylindrical portion (36) and a conical portion (40) including a seal disposed about the body of the entry fitting. An axial displacement member (46) urges the seal along the conical portion to achieve a relatively wide range of sealing force. The entry fitting can include a shield (60) positioned on the exterior of a sump to provide an access space for displacement of the entry fitting toward the exterior of the sump to allow removal and replacement of the seal without first having to remove backfill from the exterior of the sump.
L'invention concerne un accessoire d'entrée comportant une partie cylindrique (36) et une partie conique (40) et comprenant un dispositif de scellement placé autour de l'accessoire d'entrée. Un élément (46) à déplacement axial pousse le dispositif de scellement le long de la partie conique afin de produire une force de scellement relativement grande. L'accessoire d'entrée peut comporter un bouclier (60) disposé à l'extérieur d'un collecteur afin de former un espace d'accès permettant le déplacement de l'accessoire d'entrée vers l'extérieur du puisard pour permettre le retrait et le remplacement du dispositif de scellement sans devoir d'abord retirer un remblai de la partie extérieure du puisard.
