  Les diverses formes d'exécution représen  tées et décrites comprennent des têtes femel-      les     tarandées,    mais il est évident     que    la tête  4 de raccord doit pouvoir s'adapter<B>à</B> chaque  montage particulier, en constituant soit un  raccord mâle, soit un raccord lisse, soit un  raccord<B>à</B> baïonnette, soit un raccord de     toi-ut     type connu.



  Flexible hose with at least one fitting. The invention a. the object is a flexible pipe having an external helical rib and provided with at least one <B> </B> connector, characterized in that the connector comprises a deformable top screwed onto one end of the pipe and compressed on the latter by a connection head to ensure tightness (see seal.



  The attached drawing shows, <B> to </B> by way of example, various embodiments of the object of the invention.



  Figs. <B> 1. </B> and, 2 of this drawing show, in section, ten deformable rings, respectively cylindrical and frustoconical.



       The fho. ,; 1) <B> '</B> represents, in partial longitudinal section, the end of a bare pipe fitted with a fitting.



  The fies # 4-. 4 <B> to 6 </B> represent variants <B> (bed </B> pipe of fig. <B> 3. </B>



  The <B> 7 </B> and <B> 8 </B> represent another form, execution and a variant.



  In all the embodiments shown, the fitting comprises a deformable ring <B> 3, </B> which can be cylindrical (fig. <B> 1.) </B> or frustoconical (fi n-. 2) and which is screwed onto the end of the pipe and. compressed on the latter by a connection head to ensure the seal, says Joint.



       I, ë flexible pipe shown <B> to </B> in fig. <B> 2 </B> has an outer helical rib <B> 1. </B> and is fitted with a fitting comprising a ba- (truncated street ri-ide 2 and Line defor- wablP <B> ï </B> screwed onto one end of the pipe, On this assembly is engaged a partially tapped socket <B> 5 </B> in which is screwed a connection head 4, which, by an inner frustoconical face <B> 6, </B> compress the bagi:

  The deformable <B> 3 </B> on the pipe <B> 1, </B> to ensure the tightness of the joint.



  In the variant of. fig. 4, the pipe is covered # with a braid <B> 7 </B>, one end of which is wedged between the rigid ring 2 and the sleeve <B> 5. </B>



  The variant of FIG. <B> 5, </B> in which <B> the </B> fitting is also mounted on a pipe lined with a braid <B> 7, </B> comprises, in addition, a trumpet <B> 8 </B> tight with the braid <B> 7 </B> between the sleeve <B> 5 </B> and the ring 2.



  In. the variant of FIG. <B> 6, </B> the fitting is mounted on a pipe lined with a braid <B> 7 </B> and covered with a protective sheath <B> 9; </B> this one is. retained by a screw <B> 10 </B> provided by the threaded sleeve <B> 5. </B>



  The connection of the embodiment of <B> the </B> fig. <B> 7 </B> includes a deformable ring <B> 3 </B> screwed on one end of the bare pipe <B> 1; </B> the connector head 4 has a part <B> 11, </B> in one piece with the head and. cylindrical <B> at </B> the origin, crimped <B> at </B> using a frustoconical die around the ring <B> 3, </B> in order to compress the latter, on the pipe. In the variant of FIG. <B> 8, </B> this part <B> 11 </B> is a separate part 12 retained in the head by an annular rim that it presents.



  The various embodiments shown and described include threaded female heads, but it is obvious that the connector head 4 must be able to adapt <B> to </B> each particular assembly, constituting either a connector male, either a smooth coupling, or a <B> to </B> bayonet coupling, or a known type of toi-ut coupling.
