Abstract: A system for coupling at least one flexible hose is provided that includes first and second annular connecting elements. In a system mounting position, the second element is inserted partially into the flexible hose and the first element is mounted on the second element to compress the flexible hose. The first element includes a tubular body, and a proximal end having an annular part. The tubular body is divided from the annular part by axially extending openings that form at least two hooking portions with hook-shaped ends. The second element includes a first sealing projection and a second retaining projection formed beyond the first sealing projection. The second projection cooperates with the hooking portions. More specifically, the annular part comprises an annular inner protrusion to form a constriction between a bottom and top of the sealing projection side facing the said first end of the second element.

Abstract: A connector for connecting at least a first hose having a globally cylindrical wall and a second hose with each other, the connector includes at least one spigot including at least a first end configured to be connected to the second hose, and a second end configured to be connected to the first hose, the spigot allowing an hermetic fluidic connection between the first hose and the second hose, wherein the connector further includes at least one compression element being slidably movable between the first end and the second end of the spigot, the compression element being in a locking position wherein the compression element resists a compression force on the first hose at the level of the second end of spigot, in order to secure the fluidic connection.
