Abstract
An assembly is provided that includes at least one first conduit and at least one second conduit connected together through a connecting device. The connecting device includes an exteriorly threaded tube; a connecting part attached to one end of the tube and including an orifice; a holding nut screwed onto the tube and axially maintaining the connecting part relative to a tube; and a retaining member attached on the holding nut and engaging with the first conduit so as to axially retain the first conduit fitted into the orifice, the retaining member cooperating with the first conduit so as to oppose the unscrewing of the holding nut.
Claims20
A nuclear reactor comprising:
- an assembly comprising:
- at least one first conduit and at least one second conduit;
- and
- a connecting device connecting the at least one first conduit and one second conduit together, the connecting device comprising:
- an exteriorly threaded tube extending along a tube axis, the second conduit extending inside the tube;
- a connecting part attached to one end of the tube, the connecting part extending along the tube axis and being angularly indexed relative to the tube, the first conduit being fitted into an orifice which axially passes through the connecting part;
- a holding nut screwed onto the tube and axially holding the connecting part relative to the tube, the holding nut comprising a tapped annular nut body;
- and
- a retaining member removably attached on the nut body and engaging with the first conduit so as to axially retain the first conduit fitted into the orifice, the retaining member cooperating with the first conduit so as to oppose the unlocking of the holding nut.

A nuclear reactor comprising:
- an assembly comprising:
- at least one first conduit and at least one second conduit;
- and
- a connecting device connecting the at least one first conduit and one second conduit together, the connecting device comprising:
- an exteriorly threaded tube extending along a tube axis, the second conduit extending inside the tube;
- a connecting part attached to one end of the tube, the connecting part extending along the tube axis and being angularly indexed relative to the tube, the first conduit being fitted into an orifice which axially passes through the connecting part;
- a holding nut screwed onto the tube and axially holding the connecting part relative to the tube, the holding nut comprising a tapped annular nut body;
- and
- a retaining member attached on the nut body and engaging with the first conduit so as to axially retain the first conduit fitted into the orifice, the retaining member cooperating with the first conduit so as to oppose the unlocking of the holding nut, the retaining member being axially offset from the holding nut and the tube.
