For fastening terminations for telecommunication cables to walls or rails, it is known cast on the housing of the country seal or use welded-on cloths. These flaps are provided with through holes and screwed to the wall or rail by means of these penetrating screws. Condition the lobes an increased expenditure on 1 [creation costs and an increased space requirement.

It is also known in the housing wall of the Lind fastener Provide even through mounting holes and by means of these penetrating screws make the attachment. Here, however, is a special seal by means of an elastic material, especially rubber, required if the end seal is to be air and moisture-tight, as is almost generally required for telecommunication cable terminations. But now it is because of the aging of the rubber seal and the use of through mounting holes in the long run effective airtight and moisture-tight seal, as experience has shown. by no means guaranteed.

The invention is based on the object. End Locks for telecommunication cables without the disadvantageous need of fastening tabs or sealed ones Through holes to be reliably and firmly attached to a rail.

According to the invention, this object is achieved by that the housing of the end closure in each of the walls standing at right angles to one another in a corner preferably have a trapezoidal profile Has longitudinal groove and that in this zuein other parallel longitudinal grooves corresponding Engage the projections of a two-part clamping device, the parts of which are held together by means of a screw are, with the free ends of the I rush to support themselves on the rail and in the event of a solution the screw are longitudinally displaceable on this together with the end cap.

It is already known per se to attach electrical devices to a wall or rail that one no rags on the devices or screws penetrating the devices are required.

So it is known. Sockets, in particular for electric cigar lighters on motor vehicles, the housing of the socket is pushed by means of an oiler and a front flange of the socket to fasten against the fastening plate pressing compression spring, the abutment for the spring is formed by a thrust ring pushed over the socket housing, which is formed by a from the Housing the can is held pressed out cam.

For attaching an electrolytic capacitor =; it is known to have resilient tabs on a chassis plate to use an intermediate piece firmly connected to the base plate, which is essentially on the Chassis plate stand vertically and are provided with recesses or depressions, which are bulged with or wart-shaped projections on the housing of the flekrolyte capacitor cooperate.

To make it easier to insert, especially but pulling out cup-shaped, with

Plug pins provided electronic components Apparatus, which are arranged via corresponding in the apparatus chassis. Sockets mechanically with this are connected, it is known to have the module in a special frame attached to the chassis

two perpendicular to the chassis, opposite one another, resilient side parts and an implementation in the bottom of the frame to insert the opening for the connector pins. A bracket is attached to the top of the block in which a Screw is rotatably mounted. into a corresponding threaded hole in a cross rail is screwed. This cross rail has Xuten at the ends. in the grooves of the resilient side parts of the Snap the frame into place. By turning the screw 111 in one direction or another, the module pushed into the socket or pulled out of it.

The known arrangements have the disadvantage that the devices do not or not in a simple manner aul the mounting wall or rail can be moved as desired. The advantage achieved by the invention, especially with terminations, is essential part is that the end closure by loosening only one screw easily on the mounting rail

can be moved and attached in the desired position. The invention is explained in more detail on the basis of two exemplary embodiments shown in FIGS. 1 and 2 of the drawing. Fig. 1 shows the fastening of only one housing, Fig. 2 the fastening of two housings on a rail, which is effective as part of the clamping device through suitable profiling. In FIG. 1, the housing 1, which is only partially shown as an elbow, is to be fastened and is made of sheet metal, in particular sheet brass. two drawn longitudinal grooves 2 and 3 of trapezoidal cross-section, which are each made in one of the walls abutting at a corner of the housing. In these grooves, which simultaneously stiffen the housing, correspondingly trapezoidal projections 4 and 5 of two clamping bodies 6 and 7, preferably of the same width, engage. For this purpose, the clamping body 6 l) between. 7 further projections 10, 11 and 12, 13, which comprise the edges of the fastening rail 9 made of angle iron. The clamping body 6 also has a projection 14 with which it rests against the wall of the housing, in the groove 2 of which its other projection 4 engages. By tightening the screw 8, a firm connection between the clamping bodies 6 and 7 with the rail 9 on the one hand and with the housing 1 on the other hand can be established. As can be seen, there are no fastening tabs or fastening holes penetrating the housing wall. The fastening does not impair the tightness of the housing in any way - even in the long term. In addition, when the clamping screw 8 is loosened, on the one hand the housing can be displaced relative to the clamping bodies parallel to the fastening rail within certain limits. On the other hand, the clamping bodies can be moved on the fastening rail and fastened in different places. T-Is there is therefore the extensive and simple possibility of attaching the housing to the fastening rail 9 in any desired position. In Fig. 2 the sheet metal gcMuse 15 and 16 to be fastened on both sides of a rail according to Fig. 1 are provided with drawn, trapezoidal profiled longitudinal grooves 17, 18 and 19, 20 at the corner used for clamping. Corresponding projections 21 and 22 of the otherwise U-shaped fastening rail 23, which is only partially shown, engage in the grooves 18 and 20, respectively. Corresponding projections 24 and 25 of a clamping body 26 arranged between housings 15 and 16 engage in grooves 17 and 19, the lower, T-shaped part of which rests against both housings and is connected to fastening rail 23 by means of a screw 27 is. In the tightened state of this screw, the projections 21, 22, 24, 25 are pressed so tightly into the grooves 18, 20, 17, 19 ″ that the housings are firmly connected to the rail 23 a displacement of the housing relative to the rail 23 into a desired position due to the grooves is easily possible without further ado. PA TE N TANS PR Γ C II E 1. An arrangement for fastening end closures for nuclear signal cables to a rail, characterized in that the housing (1) of the end closure in each of the walls standing at right angles in a corner has a preferably trapezoidal profile having a longitudinal groove (2, 3) and that in this mutually parallel longitudinal grooves (2, 3) corresponding projections of the two-part clamping device (6, 7, 8) engage, the parts (6, 7 ) of which are held together by means of a screw (8), the free ends of the parts being supported on the rail and when the screw (8) is released, they can be moved longitudinally on this together with the end closure. 2.
