Abstract:
A connection device comprising:a body that is approximately cylindrical and has two symmetrical, opposite portions for an engagement of two tube ends, each of the portions having a hooking means to hold the tube in the connection, and a sealing means for the connection, the hooking means of each portion including: a truncated chamber arranged in each portion having a large base located near a center of the device; a longitudinal rib projecting into the truncated chamber; and a split ring having ends located on either side of the longitudinal rib, the ring having an internal threading, and an outer shape of the ring being chosen so that at least one part of its peripheral surface is supported against the truncated chamber after the engagement of the end of the tube, so as to block the tube by any traction on the tube in a direction opposite to a direction of engagement of the tube; wherein the ring is positioned free in the truncated chamber and is elastically deformable and an interior diameter of the ring is smaller than an exterior diameter of the tube in an unstressed or deformed state of the ring, so as to deform elastically and grip the tube at the time the tube is inserted.
