Abstract: A fluid circuit, in particular for an aircraft, comprising at least one first duct (1) and a first connecting member (5), at least one second duct (2) and a second connecting member (6), a connector piece (3), for joining the two connection ends of the ducts (1, 2) in a leaktight manner, comprising a central sleeve (4) configured to cooperate, at a first end, with the first connecting member (5) and, at a second end, with the second connecting member (6), the central sleeve (4) having a plurality of flexible teeth (41) in order to correct any error in alignment between the first axis (X1) and the second axis (X2).

Abstract: A fluid circuit, particularly for an aircraft, comprising a first pipe, a second pipe and a coupling comprising an outer sleeve which extends along an axis X and is mounted with the ability to slide along the axis X at a connection ends of the first pipe, a sealing member which extends along the axis X and is mounted with the ability to slide along the axis X in said outer sleeve, the sealing member being configured to sealingly connect the connection ends of the pipes, locking means configured to collaborate with a blocking member of the second pipe so as to block the translational movement of said outer sleeve towards the first pipe, the coupling being configured to move the sealing member between the two connection ends in order to provide sealing as the outer sleeve is moved as far as the blocking member of the second pipe.
