Improved connection device between a hose coupling and a rigid pipe end

摘要

This arrangement for connecting a hose coupling (1) to a rigid pipe end (6), particularly for a motor vehicle cooling system, the hose coupling being fastened in a sealed manner to the rigid pipe end by means of securing and sealing members, is characterised in that it comprises rigid tubular elements (2, 3) arranged coaxially relative to the extremity of the hose coupling (1) outside and inside this coupling respectively, in such a way that the coupling (1) is held tightly between the two tubular elements (2, 3), the fastening and the sealing of the hose coupling (1) with respect to the rigid pipe end (6) being ensured by cooperation of the tubular elements with the securing and sealing means and in that the securing means consist of a clip (7) or elastic ring comprising arms that can move elastically apart and are inserted into slots (8) passing at least partially through the wall of the pipe end (6) and are adapted to cooperate with notches (10) projecting on one of the rigid tubular elements (2, 3).
