A connection device for connecting a tubular connector provided with an annular collar to an item of equipment comprising a passage, the connection device comprising:—a connection end fitting connecting to the passage of the item of equipment, the connection end fitting being formed by a tubular body with a head mounted thereon, the head being provided with a through-opening and comprising an ellipsoidal annular groove;—a locking ring having at least two longitudinal flexible legs for insertion into the connection end fitting, each having an outer surface bearing at least one lug intended to engage in the annular groove in order to hold the locking ring secured to the connection end fitting. The two flexible legs can be deformed and closed on the tubular connector in order to abut their free ends against the collar when the male connector is inserted longitudinally into the locking ring.

According to one aspect of the present invention there is provided an adjustable connector including at least two parts, each having a main body with a bore having a longitudinal axis therein, wherein an external surface of the main body of a first part is configured to bear against an internal surface of the bore of a second part when the first part is at least partially inserted into the bore of the second part to form a connection, characterized in that the positioning of the bores with respect to the main bodies is such that when the parts are connected to each other, rotation of one part with respect to the other changes the inclination of the longitudinal axes of the bores with respect to one another.

An adjustable connector includes at least two parts, each having a main body with an angled bore having a longitudinal axis. An external surface of the main body of a first part is configured to bear against an internal surface of the bore of a second part when the first part is at least partially inserted into the bore of the second part to form a connection. The first part is prevented from rotating within the bore of the second part via a mechanical engagement of a rotational limiting feature such as a spline, key detail, or mating ridges and grooves.
