Claim:
1. A movement-constraining assembly for a fluid-conveying system, comprising: a fluid-conveying tube defining an inner passage for fluid to pass therethrough, the tube adapted to be connected to components of the fluid-conveying system at opposed ends thereof; a single blocking ring having an inner surface and an outer surface surrounding the inner surface, the blocking ring mounted to the tube with complementary surfaces between the tube and the inner surface of the blocking ring to block rotation between the tube and the blocking ring, the outer surface of the blocking ring having a first joint portion; and a base adapted to be secured to a structure, and having a second joint portion operatively joined to the first joint portion of the blocking ring to form a joint blocking at least an axial rotational degree of freedom of the fluid-conveying tube and allowing at least one translational degree of freedom of the tube relative to the structure.
