Fluid circuit, in particular for aircraft, comprising a first conduit, a second conduit and a connection, - each conduit (1, 2) comprising a connecting end (1A, 2B), extending along an axis X and defining an inner surface and an outer surface, which comprises a blocking member (12, 22) extending, radially protruding with respect to said axis X from the outer surface, the connecting ends (1A, 2B) of the conduits (1, 2) being fixed and spaced by an axial connection clearance (Jx), - the connection comprising: i. an outer sleeve which extends along the axis X and is mounted sliding along the axis X to the connecting end of the first conduit, the outer sleeve being configured to connect the two connecting ends (1A, 2B) during a movement from upstream to downstream, ii. a sealing member which extends along the axis X and is mounted sliding along the axis X in said outer sleeve, the sealing member being configured to connect sealed the two connecting ends (1A, 2B), iii. locking means, configured to cooperate with the blocking member of the second conduit to block the translation of said outer sleeve upstream towards the first conduit, - the connection being configured to move the sealing member between the two connecting ends (1A, 2B) to ensure sealing during the movement of the outer sleeve downstream up to the blocking member of the second conduit. - each conduit (1, 2) comprising a connecting end (1A, 2B), extending along an axis X and defining an inner surface and an outer surface, which comprises a blocking member (12, 22) extending, radially protruding with respect to said axis X from the outer surface, the connecting ends (1A, 2B) of the conduits (1, 2) being fixed and spaced by an axial connection clearance (Jx), - the connection comprising: i. an outer sleeve which extends along the axis X and is mounted sliding along the axis X to the connecting end of the first conduit, the outer sleeve being configured to connect the two connecting ends (1A, 2B) during a movement from upstream to downstream, ii. a sealing member which extends along the axis X and is mounted sliding along the axis X in said outer sleeve, the sealing member being configured to connect sealed the two connecting ends (1A, 2B), iii. locking means, configured to cooperate with the blocking member of the second conduit to block the translation of said outer sleeve upstream towards the first conduit, i. an outer sleeve which extends along the axis X and is mounted sliding along the axis X to the connecting end of the first conduit, the outer sleeve being configured to connect the two connecting ends (1A, 2B) during a movement from upstream to downstream, ii. a sealing member which extends along the axis X and is mounted sliding along the axis X in said outer sleeve, the sealing member being configured to connect sealed the two connecting ends (1A, 2B), iii. locking means, configured to cooperate with the blocking member of the second conduit to block the translation of said outer sleeve upstream towards the first conduit, - the connection being configured to move the sealing member between the two connecting ends (1A, 2B) to ensure sealing during the movement of the outer sleeve downstream up to the blocking member of the second conduit.
