    DEVICE COMPRISING A FLEXIBLE CRADLE
    The present invention relates to a device comprising a flexible cradle for receiving an elongate element, in particular a tube or a cable. The invention also relates to a base comprising the device of the invention and the use of said base to fix an elongated tube on a support.
    There are numerous devices for fixing elongated elements (tubes or cables for example) to a support (wall or ceiling for example). Most of these devices comprise a cradle in the form of a cavity into which a portion of the elongated element is inserted. According to some devices, the elongated element is inserted into the cradle directly by clipping. In other devices, the elongated tube is positioned in the cradle and the device further comprises a second device coming above the first to hold the elongated member.
    However, current devices have standard sizes and are therefore adapted to a specific diameter of the elongated member to maintain. Thus, a typical device does not allow to maintain a tube which has a dimension slightly greater than that for which the device is intended.
    In addition, depending on the use, the tubes are sometimes subjected to high stresses causing vibrations in the holding devices of these tubes may induce premature damage to the devices. Therefore, it would be interesting to have a device comprising at least one cradle for maintaining an elongated element while being able to adapt to elongate elements of different diameters and to absorb the vibrations induced during its use .
    However, the inventors have demonstrated that a device comprising a flexible cradle comprising a slot made it possible to meet these requirements.
    Thus, a first object of the invention is a device comprising an element comprising a flexible cradle open in a direction Z adapted to receive an elongated element, the cradle being in a longitudinal section of the device in a ZY plane, in the form an arc subtended by a middle angle to the middle, the cradle having at least one slot.
    According to the invention, an orthonormal reference (XYZ) is used in which the longitudinal section of the device defines a plane (ZY) and a direction X is perpendicular to this plane.
    In the present invention, the cradle has a particular structure which makes it possible in particular to optimally reduce the vibrations of the elongated element during its use and / or to absorb variations in the diameter of the elongated element by virtue of the presence of at least one slot.
    By "diameter variations" is meant variations of the order of 10 to 20%.
    By "slot" is meant a through opening over the entire thickness of the cradle, said slot being located in the plane (XY), preferably along the X direction in the orthonormal frame (XYZ).
