Quick connector for flexible tubes or pipes, which comprises a hollow body (1), equipped on the inside with a seating (2) for an annular seal (3), to which body is secured a collar (4) carrying a conical elastic ring (5) having radial slits open towards the inner edge, the ring diverging towards the free end of the body, into which conical ring there may be inserted a flexible tube (6) in sealing contact with the annular seal (3), which tube can be advanced towards the interior of the hollow body (1) with limited elastic deformation of the conical ring (5) and in conditions of jamming of said conical ring (5) when the tube moves outwards, there being also present a shell (8) projecting outwards from the body (1) and surrounding the flexible tube (6) and having a tapered end (11) towards the inside, the shell (8) being in contact with the internal edge of the slit conical ring (5) and being adapted for preventing, when pushed inwards into the hollow body (1), the jamming of the conical ring (5) on the surface of the flexible tube, thus making its withdrawal possible. |
