Abstract: A connecting device for flexible pipes, including: a supporting body, having at least one tubular portion which may be inserted in a relative flexible pipe; a seal ring, positioned around the tubular portion of the supporting body and switchable between an engaging position wherein it retains the flexible pipe on the tubular portion and a releasing position wherein it disengages the flexible pipe; and a mechanism for moving the seal ring for switching the ring between the engaging position and the releasing position; the tubular portion of the supporting body also including at least one protruding element, extending from the outer surface of the tubular portion along the entire transversal extension of the portion; the protruding element being interposed between two adjacent zones of the tubular portion having different transversal cross-sectional dimensions.

Abstract: A device for connecting flexible hoses comprises a connecting member (2) having a tubular element (4) that can be inserted into a flexible hose (T). The tubular element (4) and a radially external threaded cylindrical member (5) together delimit an annular seat (7) designed to accommodate an end (T1) of the flexible hose (T). A threaded ring (10) can be screwed onto the cylindrical member (5) and accommodates a split bush (15) having a working surface (16) engaged with a working surface (14) of the ring (10). By turning the threaded ring (10), the split bush (15) can be moved between a position where it is axially spaced from the threaded cylindrical member (5) and a position where it is axially close to the threaded cylindrical member (5) and where an interposed seal (18) between the cylindrical member (5) and the bush (15) adopts a radially inwardly deformed condition such as to tighten it around the flexible hose (T).
