The invention is explained in more detail on the basis of an »exemplary embodiment in the following description.

Truncated cone cooperating opening area in F i g. I is a male part P according to the invention

provided with longitudinal slots, made of resilient resilient 60 shown, namely in the form of a multiply dispensed material, preferably plastic, consisting set rotationally symmetrical, one-piece EIe sleeve is formed, whereby the Mentes when inserted at the front, which is preferably formed from a suitable lying truncated cone is acute-angled Plastic is made. The lower part of the patrix as the opposite truncated cone of the double wedge part P is an un-open, hollow fastening truncated cone. 65 fen S is formed, on the outer circumference of which there are four

Such plug connections with a conical tooth-like profile rings 4 are formed in such a way that frustum-shaped mandrel, which is in a correspondingly out of the fastening pin 5 with its end first formed sleeve engages are known. To push such a slightly into a cylindrical bore, however

Can hardly or not at all be pulled out. A cylindrical neck piece 11, which merges into a dome 10, adjoins an upper end face 4 α of the uppermost profile ring 4. This is designed as a double double truncated cone; the front double truncated cone has a slender truncated cone 12 and a truncated truncated cone 14 offset downwards, and the rear double truncated cone has a slim truncated cone 12 'and a truncated truncated cone 14' which is also offset downwards. Above the front, slender truncated cone 12, a blunt tip 34 forms the end of the dome 10.

A female part M that matches the male part P described above is shown in FIG. 2. This die part M has a likewise hollow fastening pin 8 with four sawtooth-like profile rings 7, and a cylindrical sleeve piece 15 connects to the uppermost profile rear, the inner walls of which are essentially adapted to the contours of the ao dome 10 described above. Inside the sleeve bore there is a slender hollow truncated cone 17 which, in the assembled state, rests on the slender truncated cone 12 of the dome 10; This is followed by a truncated hollow truncated cone 16, which merges into a slender hollow truncated cone 17 ', which in turn is followed by a truncated hollow truncated cone 16', to which an opening in the sleeve bore is finally adjoined by a rounded cylindrical centering piece.

F i g. 2 shows the die part M in a section which runs through the axis of rotation of this element, which is also preferably made of plastic. In the front part of the sleeve 15 there is a slot 51 which runs perpendicular to the plane of the drawing and is of course also located in the sleeve half that has been cut in the front.

Claims (2)

1 2 to be able to release connections non-destructively, claims: zen the sleeves interacting with the mandrel are opposite slots, which extend through The i extend 1. plug connection, in particular for starting connects over the length of the entire Hüisenbereiches of wood, stone, marble, concrete and metal, in which the double cone of the dome allteilen to "consisting of two detachably snap in- Is brought into place. However, this known connector interlocking at the pitch to be connected has the disadvantage that in the case of a lateral joint fastened connection elements, of which bending and / or shear stresses the sleeve, the one element (male mold) as one with at least one in the ski area opens slightly, releasing the mandrel in a widened, truncated double cone-shaped io. In order to achieve greater strength, the mandrel provided with the head and the other element a loosening of the plug-in connection; it is also already in the case of the matrix) as a mandrel that encompasses this mandrel head according to the domestic, several truncated cones engaging one behind the other, with a collar-like mandrel. For the subsequent soldered edge engaging behind, at least in the connection with the sen, slots are arranged in the die at double truncated cones cooperating openings, which extend from the edge over several opening areas provided with longitudinal slots and comprising truncated cones. In the case of resilient, resilient material, preferably a plug-in connection with a single double-sided plastic sleeve, it is known to open the slot only in the area at dw. when inserting the truncated cone of the double truncated cone at the front, is more acute-angled than the opposite in any direction, its predesigned (P) two or more successively agreed resistance to reading essentially ordered double truncated cones (12, 14; 12 ', 14) remains unchanged. 35 According to the invention, this object is achieved by solving these double truncated cones individually in the case of the male mold, in that two or more rear inter-engaging nub profiles (16; 16 ') are arranged in front of each other, and in the case of the female part (M) which are seen, and that the longitudinal slits (51, 52) matrix matched several, these double piping matrices (M) are so arranged that each gel stump individually behind-reaching internal profiling longitudinal slot is only provided with a double cone 30 gene, and that the longitudinal slots the blunt (12, 14 or 12 ', 14') uer patrix (P) to matrix are arranged so that each longitudinal slot is ordered. only one double truncated cone of the patrix to ■ 2. Plug connection according to claim 1, characterized in that it is arranged. A particularly advantageous embodiment indicates that the respective double kinks of the plug-in connection according to the invention can be achieved with stumps (12, 14; 12 ', 14') when the double-cone slots (51, S 2) of the die (M ) slots of the die assigned to stumps are arranged offset from one another, the one being offset from the other, with the slots assigned to the one double truncated cone partially trize in the same circumferential area (Y) of the maize in the same circumferential area of the die (M) are arranged like the other 40 like the slots assigned to the other double truncated cone to double truncated cone slots.
