Patent attributes
An instantaneous connection device includes a tubular body, a tight element used to hold the end of a line in the body and includes an elastically deformable annular sealing element and a holding element that are arranged to receive the end of the line, a cam member for moving the holding element from a free state into a state wherein it grips the end of the line when it is axially displaced in the tubular body from a first position to a second position, and an elastic member for bringing the holding element back towards its second position. The sealing element is mounted between a radial shoulder of the body and a radial face of the holding element. The radial shoulder and the radial face are provided with reciprocal reliefs for laterally coming into contact with the annular sealing element.
