Device for flexible hoses of the kind, which internally and/or externally are reinforced by means of a coil spring (11, 19) or the like for preventing the hose (10) from collapsing at flexure. The spring (11, 19) is attached to an internal socket-shaped nipple (12) and/or an external socket (17) only at one end. The socket is arranged to be connected to one end portion of the hose through forced fitting. The spring (11, 19) is provided freely movable in and/or on the hose. The spring (11) is screwed firmly on the nipple and compressed before insertion in the hose (10), and it is inserted in the hose in compressed condition, after which the spring is decompressed. |
