According to such an embodiment, the Ü-ehäusehälften 13 and 2o have a thickness of approximately 3 minutes, approximately a width of 25 now and approximately a total length of 32 now mm contains 1.5 min. Correspondingly, each platform-like section of the housing halves 18 and 20 has a recess of approximately 0.75 mm by 12.5 minutes. The projections 42 are similarly shaped so that they abut one another when the G-housing halves are assembled so as to engage a hole 44 compressed in the cable 12.

The stainless retaining sleeves 22 and 24 have an inner diameter of approximately 0.33 mm so that they can open the fibers 14 and 16 '. The fibers are in it by an _o eei _o iieten ilarz, such as z.ß. Ispoxy resin type 96-083 from Dow Corning Corporation Defestigt. . In the preferred embodiment according to i'ig. 1, the flanges 60, 62, 64 and 66 have an outer diameter of approximately 4.5 mm and an inner diameter which enable them to be press-fit into the steel pipe.

The connection device also has a printed circuit board So on which electronic circuit components are provided depending on the desired application. The connector device 78 further includes a pair of fiber retaining elements 92 and 94 in which short optical fibers 96 and 98 can be anchored to provide optical coupling of associated optical elements in the electronic circuit unit 9o and optical fibers in the first connector device 1o . The housing halves 80 and 82 are formed from a suitable plastic such as a polycarbonate resin or the like. Each half has at least one protruding pin 100 and a corresponding opening 1o2, so that when the halves are assembled, the pin 100 of one G housing half is received in a corresponding opening 1o4 in the opposite housing half. The cover plate 86 is also injection molded from a suitable plastic and has a number of protruding pins 106, 100 and Ho. The pins are inserted into matching openings 112, 114 and 116 in the side legs of the elements 80 and 82. The base element 84 is similarly freely provided with a number of openings through which the pins correspond to the pins Iodine, 108 and Ho when the Connection device can be used. Following assembly, the protruding pins for a

A rear end portion 113 to the top plate 86 closes the rear part of the E _n <lverSchlusses 78, wherein access to electrical terminals 12ο 9o is possible for a terminal of the electronic .Baueinheit. The retaining elements 92 and 94 are essentially identical to the retaining elements 22 and 24 of the first connection device Io and are made from a stainless tube which is arranged in a press-fit fashion in kessing flanges 124 and 126. These elements are in suitably shaped recesses 123 and 13o in the deiiluseiiälften Jo and 32 a ^ eptuit, so aais daa stlrnende over the one Jtirnteil 131 of the G-ehäusehälften do and 32 protrudes.

Ends of elastic fingers 72, 74, 76 and 78 of the first connecting device record to the connection device with each other to lock and hold the respective retaining elements in abutment and in axial alignment in alignment elements 26 and 28.

While the elements shown in Fig. 1 can all be made of plastic by injection molding, in a particularly preferred embodiment, the .Base element 84 made of a thermally conductive metal or the like. Manufactured and with! be provided with a corrugated outer surface to provide additional heat dissipation. In such a case, the printed circuit board 6 can suitably be made of an insulating material such as an electronically insulating quality kei-caik.

In the case of the fi _e in the right hand side. 1, the alignment members 26 and 2o are provided in the housing halves 18 and 2o and the retaining members 22 and 24 are inserted into one end of the alignment members 26 and 28. When the connection devices 10 and 18 are joined together, a second set of retaining elements 92 and 94 is the paired connection in the housing halves 8o and 82; device 78 is held, inserted into the alignment elements 26 and 23 in such a way * that the end parts of both sets j of the retaining elements abut one another, whereby an optical
