Abstract

Ce collier est du type destiné à être adapté sur un gazoduc où, de façon générale, sur un tuyau, afin par exemple d'insérer ce tuyau dans un autre sans risque d'endommager le revêtement appliqué sur le tuyau de plus petit diamètre. Il est constitué essentiellement par une bande souple d'épaisseur adéquate qui est enroulée autour d'u tuyau, les extrémités de la bande étant munies de rangées de dents parallèles à son axe, de sorte que Ces extrémités puissent être insérées l'une dans l'autre par engrènement mutuel des dents de ces rangées, ces dents présentant un profil qui se prête à cette insertion et qui empêche une séparation. Ce collier est de conception plus simple et d'utilisation plus pratique que celles des colliers connus jusqu'à ce jour.This collar is of the type intended to be fitted on a gas pipeline or, in general, on a pipe, for example in order to insert this pipe into another without risk of damaging the coating applied to the pipe of smaller diameter. It consists essentially of a flexible strip of adequate thickness which is wound around a pipe, the ends of the strip being provided with rows of teeth parallel to its axis, so that these ends can be inserted one into the pipe. 'Another by mutual engagement of the teeth of these rows, these teeth having a profile which lends itself to this insertion and which prevents separation. This necklace is of a simpler design and more practical use than those of necklaces known to date.
