ABSTRACT:
A fluid transport circuit element comprising a body having a bore with one end fitted with a pipe end coupling device, the coupling device having a portion fitted with an anchor washer for anchoring the device in the bore, the washer being deformable between an anchor state and a free passage state, and wherein the portion fitted with an anchor washer is drivable from outside the body in the insertion direction into the bore from an anchor position in which the washer is in its anchor state and a release position in which the washer co-operates with an abutment that is stationary relative to the bore in the insertion direction, thereby bringing the washer into its free passage state in which it is retained by a retainer.
