Thermally-insulating connecting elements for coupling two component parts, and also compound, thermally-insulating profile members and a process for their manufacture

A thermally-insulating connecting device intended for the coupling of two components and comprising a first connecting element which is insertable into receiving channels on the components, said connecting element being shaped for engagement within said receiving channels as a result of its shape and provided with ridges fitting into slots of the components, and further comprising a hammer headshaped second connecting element which is adapted to be locked with the first connecting element by a removable clamping means, and which has inclined wedge surfaces cooperating with corresponding inclined surfaces of projections of the components so that a connection of the components is formed by a wedge action between the second connecting element and the components, a third connecting element disposed symmetrical to the second connecting element and comprising corresponding wedge surfaces and catching means, the dimensions of the second and third connecting elements being chosen so that in the operating position thereof an air space remains between the extensions of said connecting elements and the bottoms of the corresponding channels of the components.

A thermally-insulating connecting device intended for the coupling of two components and comprising a resiliently deformable connecting element which is insertable into receiving channels on the components, said connecting element being shaped for engagement within said receiving channels and, after having been inserted into said receiving channels, to be changed in its dimensions by inserting a locking element so that a connection of the components is formed by resiliently deforming said connecting element by means of said locking element, to urge said connecting element against interior walls of each of said receiving channels and position said channels by interaction of (i) a wedging force urging said channels toward each other and (ii) maintaining said channels at a desired distance from each other, said locking element comprising a tool adapted to be removed after mounting the connecting device.
