| | shrink-fit stop | Explanation:
When you say "shrink fit" you tend to think of plastic wrapping heat shrunk over articles, but the same can be done with metals. take a rod, for example, and a ring that ALMOST slides over the rod. By heating/chilling the rod and the ring to appropriate temperatures to achieve relative expansion/contraction the ring can be placed over the rod and positioned where required. When the parts return to their normal temperatures, they will be tightly locked together.
Quite what the purpose of such a stop on pipework might be I cannot fathom, however.

L'ASSEMBLAGE PAR EMMANCHEMENT OU FRETTAGE consiste à rendre solidaires une bague et un axe, le diamètre intérieur de la bague étant usiné légérement plus petit que le diamètre extérieur de l'axe pour obtenir le serrage fonctionnel de l'assemblage.
Le mode d'assemblage par frettage est très répandu, du fait du perfectionnement des moyens d'usinage. En effet il devient possible d'assembler des pièces métalliques de grande précision dimensionnelle telles que des canons, des roulements, des BAGUES D'ARRÊT, etc ...

| Grading comment Many thanks for your help. In the end, I received confirmation from customer that "shrink-fit ring" would be their preferred choice.
In any case, many thanks for your help.
