Zusammenfassung:A joint having a male joint member and female joint member, in which a raised stop on the male joint member is limited to displacement between a constriction on the female joint member and a locking ring segment, and in which the locking ring segment and constriction are separated by an unobstructed traverse region that allows the male joint member to slide axially when under stress without separation from the female joint member. The rounded shape of the groove that accommodates the locking ring segment acts like a universal joint, allowing deflection between the male and female joint members without separation. The female joint member flares on the inside of its distal region to accommodate such deflection. Thus the male and female joint members have a degree of axial and radial flexibility that prevents separation under stress, such as during earth movement events such as earthquakes, floods, and landslides. L'invention concerne un joint comprenant un élément de joint mâle et un élément de joint femelle dans lequel le déplacement d'une butée en relief sur l'élément de joint mâle est limité entre un étranglement sur l'élément de joint femelle et un segment de bague de verrouillage, le segment de bague de verrouillage et l'étranglement étant séparés par une région transversale libre qui permet à l'élément de joint mâle de coulisser de façon axiale lorsqu'il est sous contrainte sans séparation de l'élément de joint femelle. La forme arrondie de la rainure qui accueille le segment de bague de verrouillage agit comme un joint universel, permettant une déviation entre les éléments de joint mâle et femelle sans séparation. L'élément de joint femelle s'évase sur l'intérieur de sa région distale pour accueillir ladite déviation. Les éléments de joint mâle et femelle présentent un degré de flexibilité axiale et radiale qui empêche la séparation sous contrainte, comme lors de catastrophes naturelles telles que des tremblements de terre, des inondations et des glissements de terrain.
