Abstract

L'invention concerne un dispositif de raccordement (7) pour un circuit d'air d'un moteur d'aéronef, comportant deux embouts, respectivement mâle (14) et femelle (13), configurés pour être engagés par translation axiale l'un dans l'autre, les embouts étant aptes à se déplacer axialement voire radialement l'un par rapport à l'autre en fonctionnement, caractérisé en ce qu'il comprend en outre un soufflet annulaire (19) s'étendant autour desdits embouts (13, 14) et comportant une première extrémité axiale fixée de manière étanche sur l'embout mâle (14) et une seconde extrémité axiale opposée fixée de manière étanche sur l'embout femelle (13), ledit soufflet annulaire (19) étant apte à se déformer élastiquement pour autoriser les déplacements relatifs desdits embouts.The invention relates to a connection device (7) for an air circuit of an aircraft engine, comprising two end pieces, respectively male (14) and female (13), configured to be engaged by axial translation one in the other, the end pieces being able to move axially or even radially with respect to one another in operation, characterized in that it further comprises an annular bellows (19) extending around said end pieces (13 , 14) and comprising a first axial end fixed in a sealed manner on the male end piece (14) and an opposite second axial end fixed in a sealed manner on the female end part (13), said annular bellows (19) being adapted to be elastically deform to allow the relative movements of said end pieces.
