ABSTRACT:
A connection fitting for a corrugated tube includes a cylindrical housing, a bow-shaped locking element attached to the housing by a hinge portion and a corrugated tube for insertion into the housing. The cylindrical housing has two openings and a wall element between them for receiving a bow-shaped locking element provided with two pairs of ribs on its inner surface corresponding to the openings. When inserting the corrugated tube into the cylindrical housing, the corrugated tube is fixed firmly to the cylindrical housing by the ribs on the locking element engaging with the groove portions of the corrugated tube through the openings.
