ABSTRACT:
A connection fitting for a corrugated tube has a cylindrical housing for receiving the corrugated tube and a U-shaped locking element for fixing the corrugated tube firmly to the cylindrical housing. The cylindrical housing is provided with a sunken portion on the side surface and slits running circumferentially at a bottom of the sunken portion. The locking element has ribs projecting on its inner surface which penetrate into the slit and engage with the grooves of the corrugated tube. The engaging members are formed on both sides of the sunken portion of the cylindrical housing. Corresponding hook-like elements are formed at both ends of the locking element.
