Abstract

A connection system for interconnecting a heat exchanger and a pipe union, in which the pipe union (5) opens out into a connection tube (4) of a heat exchanger water box (3), with the pipe union being fixed to a flexible pipe (6) via a permanent connection and being fixed to the connection tube via an easily-released resilient connection. The resilient connection is constituted by a locking device comprising two diametrically opposite fingers (19) carried by a ring (18) fixed inside the water box (3) and disposed coaxially with the connection tube (4). The fingers (19) slope towards the axis of the connection tube and they are resilient in the radial direction, with two notches (22) being provided in the leading end (7) of the pipe union (5) in order to receive the locking resilient fingers (19) by snap-fastening when the pipe union (5) is engaged in the connection tube (4). The invention is applicable to providing rapid connections in the automobile industry.
