Apparatus for cooling liquids, especially lubricating oil for internal combustion engines or heat engines, etc., including a heat exchanger formed by at least one tube for circulating said liquid to be cooled, immersed in a cooling liquid. The exchanger is connected to the outside circuit by connectors passing through the wall of the container of the cooling liquid. These connectors are formed in two parts, one of which projects externally, said parts being so shaped that when assembled they jointly form an annular cavity which surrounds the edge of the opening formed in the container wall; the volume of said cavity diminishes gradually when said two parts are joined together whereby to confine and tighten a flexible seal placed within said cavity.
