Abstract
This invention relates to an element for rapid connection between a supple hose pipe, for example, made of rubber, and a tube made of rigid material, such as metal, or semi-rigid material, such as a plastic material. It is constituted by an assembly of an inner and outer bush tightened around the hose pipe. A housing for an O-ring is partially formed on the inner surface of the inner bush. The housing is closed by an annular radial wall distinct from the inner bush. A tube is immobilized in the element by a split ring which provides a stop for a shoulder located at the end of an annular ramp provided on the tube. The split ring is located in a annular housing formed partly by the radial portion of a distinct bush.
