The element comprises a lower shell (100) and an upper cover (150). The lateral walls (110,160) have several semi-circular corresponding notches (50) defining, once the cover is closed over the shell, circular openings for corrugated tubes. These notches (50) are fitted with a series of flexible fingers (10) in the form of circular sectors constituting, for the openings, flexible screens in the form of a circular crown. <??>Each internal semi-circular rib (40) for the longitudinal locking of corrugated tubes is situated on a small tongue (30) in the shape of a circular arc lying in a plane parallel to the corresponding opening, which small tongue is linked either to the inner wall by a flexible arm (20) or to the bottom at its lower mid part. <IMAGE> |
