Abstract
In a rapid connecting device for coupling a tube member with a connector such as a terminal connector on the end of a pipe, the tube member is of the type having an annular groove. The connecting device comprises a collar piece which is adapted to be mated with the tube member, around the latter, the collar piece having a locking means for engaging in the annular groove of the tube member so as to immobilise the collar piece with respect to the latter. The connector has a socket arranged to receive the end portion of the tube member and the collar piece, with a seal being interposed between the collar piece and the tube member. The collar piece has a further locking means for immobilising the connector with respect to the collar piece. The invention is especially applicable to the coupling of heat transfer fluid inlet and outlet tube connections of a heat exchanger, with external pipes.
