Abstract: A connector (1) for connecting two tubes (5, 6) by cooperation between a first element (3) fixed to a first tube (6) and a second tube (2) forming a sleeve for a second element (5) fitted at its end with a flared part (50, 51, 52, 53) by a claw (4) including a spring (44) compressing the said flared part. The said claw (4) forms a first cylindrical guide ring (40) sliding on the external cylindrical surface (32) of the first element (3) and has a recess (41) forming a cage for the spring (44). A second cylindrical guide ring (42) is fixed to the first ring (40) and sliding on the external surface (21) of the second element (2), and including a device (43) for locking/unlocking the second element (2) and the second cylindrical ring (42).
