Il.est évidemment connu de réunir des morceaux de canalisation par divers moyens. A titre d'exemple, la moitié mâle présente souvent une conicité à l'extrémité de laquelle s'adapte l'élément femelle. De tels joints sont opérants mais manquent-de flexibilité et d'étanchéité. Des modifications à des joints de ce genre englobent ceux dans lesquels un rebord est prévu sur l'élé- <EMI ID=2.1>

Si on se reporte à la 'Figure 2 , un joint de canalisation 1 est composé d'un élément mâle 2 et d'un élément femelle 3. L'élément femelle 3 comporte une section large 4 et un flasque 7 formant entre eux une rainure 8.

  "Seals for pipes"

  
 <EMI ID = 1.1> plastic res.

  
It is obviously known to bring together pieces of pipe by various means. For example, the male half often has a taper at the end of which the female element fits. Such seals are operative but lack flexibility and tightness. Modifications to such joints include those in which a flange is provided on the element- <EMI ID = 2.1>

  
 <EMI ID = 3.1>

  
 <EMI ID = 4.1>

  
 <EMI ID = 5.1>

In previous devices of this general type,

of the male element and the shoulder of the female element. This inter-

spills entrained in the fluid circulating in the pipe. As a result, such joints are subject to obstruction and that

  
the flow is thus limited.

  
An object of the present invention is therefore to provide a joint for a pipe, which has inter-

  
 <EMI ID = 8.1>

  
accumulation of any entrained solids.

  
An object of the present invention is also to provide a pipe seal, which not only ensures good sealing but also allows axial adjustment.

  
In the implementation of the present invention, pre-

Preferably, the base of the flange was substantially flush with the base of the wide section.

A feature of ,, the present invention is also that it is not necessary .. for the end of the element 2 to be in effective contact with the bottom of the groove 8. As the seal is produced by the ring 6 fitting into the retainer 5, a large amount of adjustment is possible without
