Abstract: A connector for connecting to a tube is provided. The connector includes a head, a slide provided with a passage orifice, and a seal ring disposed between the head and the slide. The head includes a housing capable of receiving a first end of the slide. The slide received in the housing includes: a first position, called assembly position, in which the slide is capable of receiving a tube via a second end of the slide such that the tube passes through the seal ring; and a second position, called working position, in which the seal ring is likely to be compressed by the first end of the slide. The slide is displaced from the first position to the second position under the effect of a thrust force.

Abstract: A connection device for connecting at least one pipe and a base and topped by a collar comprises a connection end piece for fluidly connecting the pipe to the base and a retaining ring for keeping the connection end piece assembled with the base. The connection end piece comprises a tubular body and at least one first retaining element. The retaining ring comprises an annular body provided with a second retaining element engaging with the first retaining element to retain the retaining ring on the connection end piece. The retaining ring also comprises at least one locking tab integral with the annular body in order to grip the collar and keep the retaining ring assembled with the base.

Abstract: A tube coupling including a female connector a body into which a male connector having an annular collar is inserted axially, and a connection element is provided. The connection element extends in a transverse direction within the body of the female connector. The connection element is designed to interfere mechanically with the collar during insertion of the male connector and to move transversely of its own accord towards the inside of the female connector. The connection element includes a locking hook that co-operates with a locking catch provided in the female connector. The hook goes past the catch as a result of the mechanical interference of the collar that drives axial and radial elastic deformation of the connection element. The hook locks against the catch when the connection element is fully pushed into the female connector.

Abstract: A tubular coupling comprising a female connector (2) into which a male connector (6) provided with an annular collar (7) is designed to be inserted axially, and a connection element (9) that extends in a transverse direction in the female connector. The connection element is designed to interfere mechanically with the collar while the male connector is being inserted into the female connector, and to move by itself in said transverse direction towards the inside of the female connector. In addition, the connection element and the female connector are also designed so that, after the reaction to the radial resilient deformation of the connection element on the collar of the male connector, they come to bear against each other in the manner of a projection (14) that, by resilient return, exerts pressure on a guide ramp (15), so as to generate a thrust force that extends the movement of the connection element towards the inside of the female connector.

Abstract: A fluid communication device including a tubular body which enables the circulation of a fluid and which has an end piece that is connectable to a plug-in pipe having an outer annular locking groove. An assembly head includes a receiving chamber in which an end piece of the tubular body is mounted. The assembly head includes a U-shaped locking element having two arms that are inserted into the receiving chamber. An intermediate ring is slidably mounted in the receiving chamber to achieve a pre-opening of the locking element just before the plug-in pipe reaches a position in which it engages with the end piece.

Abstract: A coupling for a connector for fluid pipes includes a female base in which a male end-piece is inserted to produce a sealed connection. An elastically deformable C-shaped metal wire spring immobilizes the end-piece in the base. A locking sleeve is movable axially around the spring and the base between a first axial position in which the spring can deform radially towards the outside of the base, and a second axial position prohibiting the radial deformation of the spring. The sleeve has at least one radial interior recess into which the spring retracts when deformed by the end-piece in the first position. Each recess is offset axially with respect to the spring in the second position, preventing the radial deformation of the spring and thereby safeguarding the sealed connection.

Abstract: A crawling (2) for a connector (1) for fluid pipes comprises a female base (4) in which a male end-piece (3) is inserted in a certain axial direction (A) to produce a sealed connection, an elastically deformable C-shaped metal wire spring (5) for immobilizing the end-piece in the base, and a locking sleeve (6) which can move axially around the spring and the base so as to occupy a first axial position (P1) in which the spring can deform radially towards the outside of the base, and a second axial position (P2) prohibiting the radial deformation of the spring. The sleeve has at least one radial interior recess (12A, 12B) into which the spring retracts when it is deformed by the end-piece and when the sleeve occupies said first position. Each recess is offset axially with respect to the spring when the sleeve occupies said second position, preventing the radial deformation of the spring and thereby safeguarding the scaled connection.

Abstract: The invention relates to a connection device (10) comprising: a socket end (12), a spigot end (11) which is intended to be inserted into the socket end (12) and a locking member (18) which is intended to hold the spigot end (11) in the socket end (12) once they have been connected. The locking member (18) is shaped in the form of a staple comprising a head with two side arms. The spigot end (11) comprises an actuating cone which is used to lift the locking member (18) and to position the spigot end (11) between the arms of the locking member (18). The locking member (18) preferably comprises a deformable tongue on each side arm. The deformable tongues form elastic return means which return the locking member (18) to the locked position and block the spigot end (11) in the socket end (1) in the end-of-insertion position.

Abstract: A coupling comprises a socket member (1) and a sealing ring (10) that is fixable in a receiving space (4) adapted to receive an insert member (13) insertable into the socket member (1) in an insertion direction. In assembled arrangement, the sealing ring (10) bears against mutually opposite contact surfaces (9, 11), said contact surfaces (9, 11) lying partially outside a plane oriented at right angles to the insertion direction. The insert member (13) thereby comes into contact first with front portions and then gradually with rear portions of the sealing ring (10), such that appreciably lower insertion forces are required because of the porportionately low static friction forces.

Abstract: A tube coupling including a female connector a body into which a male connector having an annular collar is inserted axially, and a connection element is provided. The connection element extends in a transverse direction within the body of the female connector. The connection element is designed to interfere mechanically with the collar during insertion of the male connector and to move transversely of its own accord towards the inside of the female connector. The connection element includes a locking hook that cooperates with a locking catch provided in the female connector. The hook goes past the catch as a result of the mechanical interference of the collar that drives axial and radial elastic deformation of the connection element. The hook locks against the catch when the connection element is fully pushed into the female connector.
