    Patent number: 5284368
    Abstract: A tube connection consisting of a nipple structure and a sleeve member in which the nipple structure includes a tube-receiving portion provided, starting from an abutment surface with a substantially cylindrical section and an outwardly flaring clamping surface. The sleeve member is provided with a first internal section of substantially cylindrical shape followed in the direction toward the free end of the tube-receiving portion with an outwardly flaring clamping surface, whereby the internal diameter of the cylindrical section of the sleeve member is only slightly larger than the maximum diameter of the tube-receiving nipple portion. In one embodiment, the nipple structure and sleeve member are provided with complementary locking means to enable locking of the sleeve member in the clamping position by axial movement in the direction of the free end of the tube-receiving nipple portion and subsequent rotation of the sleeve member into predetermined locking position.
