ABSTRACT:
A heat exchanger comprises a fluid inlet tube member and a fluid outlet tube member on parallel axes, and third and fourth tube members to be coupled end-to-end to the inlet and outlet tube members, for connection of the latter to external flexible tubes; and has a rapid coupling device which comprises two sleeves, constituting end portions of the third and fourth tube members, for embracing the fluid inlet and outlet tube members, which are provided with seals. A locking arm which is pivoted on one of the sleeves terminates a saddle which, in a locking position, extends through an aperture in the other sleeve so as to be engaged on the outlet tube member and to hold the latter in sealed contact with the second sleeve. The arm at the same time maintains the first sleeve in sealing contact with the inlet tube member, which is fixed with respect to the outlet tube member.
