The device for connecting a length of duct to a coupling endpiece of an apparatus or a member includes at least one tubular sleeve having two portions in axial succession, the first portion being internally fitted with components of an instant connection coupling for the end of a length of duct, the second portion including means for sealably and releasably covering the coupling endpiece, the end face of the endpiece forming an axial abutment at the end of the length engaged in the first portion of the sleeve.

A connection device for releasably connecting an end section of a length of duct to a tube fitting body, said body having a tubular end coupling portion limited by a front distal face and provided with external first attachment means adjacent to said front distal face, said device including: a generally tubular sleeve in which, a first axial section of the sleeve has second attachment means for releasably cooperating with said external first attachment means of said end coupling portion, a second axial section of the sleeve integral with said first axial portion has radial grip means for instant connection of the end section of said length of duct to said sleeve, said grip means including a deformable element which is deformable between an operative shape and an inoperative shape, said second axial section having an internal surface facing said front distal face so that when said external first attachment means of the end coupling portion is fully engaged with the second attachment means of the sleeve, said internal surface of said second axial section and said front distal face are in an axial relative position such that said deformable element is in operative shape, said front distal face and said internal surface being the operating means for deforming said deformable element, wherein said front distal face is planar, perpendicular to the axis of said tubular sleeve and constitutes an abutment for the end section of the length of duct when inserted axially in the sleeve.
