ABSTRACT:
A connector for corrugated tubes comprises a lower shell (100) and an upper cover (150) having lateral walls (110, 160) with several corresponding semi-circular openings (50) that define, when the cover has been closed on the shell, circular openings for receiving corrugated tubes. The openings (50) are fitted with a series of flexible fingers (10) in the form of truncated segments of a circle that form flexible skirts in the form of a circular crown around the openings. Internal semi-circular ribs (40) for longitudinally locking the fitted corrugated tubes are situated on arcuate tongues (30) arranged in a plane parallel to the corresponding opening. Each tongue (30) is connected either to the inner wall by a flexible arm (29), or to the bottom of the shell by its lower middle part.
