To connect electrical lines 1 to a mounting surface, such as a wall Or ceiling surface, furniture or the like, to be able to securely fasten electrically according to the invention for this purpose cable clamps are used, each consisting of an im Cross-section of a U-shaped fixing part 2 made of plastic and a U-shaped cross-section Assemble clamp part 3 made of metal. The U-shaped fixing part 2 overlaps with its U-space the electrical line 1 and thus forms opposite the metallic Clamp part 3 is an insulating piece, which in addition to the liner insulating effect also fixes the position the line 1 causes.

The U-like clamp part 3 grips over the fixing part 2 and its longer U-legs designed as the fixing part legs are inserted into the fastening surface knocked in so that both parts 2, 3 result in a cable clamp unit. For guidance and secure connection of the two parts 2, 3, the fixing part 2 has at least in the area of its U-web one running over the entire length of this U-web Receiving channel 4, in which the clamp part 3 is inserted with its U-web guided in position.

In order to efficiently process the individual parts of the invention To be able to carry out cable clamps, it is advantageous to combine the fixing parts2 in one Form strand 5, wherein the fixing parts 2 can be separated from the strand 5 individually. The fixing parts 2 are through thin-walled connecting webs 6, which are preferably lie on the free leg ends of adjacent fixing parts 2, held together to form the strand 5.

The chamber parts 3 are also formed in strand form and they can be separated from this strand 7 individually. The parentheses 3 are here punched in a known manner in a U-profile, so that between them another there is a very thin-walled connection that is easily detachable.

For the separation of the fixing parts 2 and clamp parts 3 from their strand 5, 7 and the joining and shooting of the two parts 2, 3 to a fastening surface the device according to the invention has been created, which as a Anschießgerät on his Housing 8 has a magazine, which two superposed, against each other receiving channels 10 divided off and opening into a common imposition space 9, 11 for one strand 5, 7 each.

The lower channel 10 receives the fixation part 5 and in the overlying and parallel to the lower channel 10 running channel 11 becomes the clip part strand 7 introduced.

The upper clip part channel 11 is of a U-profile 12 with after formed downwardly directed opening, so that the U-space gives the channel 11. At this U-profile 12 is a second channel 10 on the opened U-side, which results in the fixing part channel U-profile 13 arranged, which is slidably mounted on the upper U-profile 12 is and thus closes the clip part channel 11 and for introducing a clip part strand 7 opens.

The lower U-profile with its U-opening also pointing downwards 13 is closed by a slide 14 mounted on the opening side, the the lower channel 5 also opens for the introduction of a fixing partial strand 5.

The two superposed U-profiles 12, 13 have on the free ends of their U-legs each have a laterally outwardly protruding bearing web 15, 16 and on the two bearing webs 15 of the upper profile 12 is the lower profile 13 with a cross-sectionally C-like guide piece which forms the profile transverse web 17 slidably mounted.

The slide 14 also has a C-like cross section and engages via the two bearing webs 16 of the lower profile 13.

The upper U-profile 12 ends directly at one of the usschieR space 9 forming Guide head 18 and the lower profile 13 and the slide 14 are at the ends Stops 13a, 14a can be moved against this guide head 18. The guide head 18 has at the bottom a U-shaped guide piece 19, with which he over the to be fastened electrical line 1 engages, thereby providing a guide for attaching the Cable clamp is given.

A sliding piece 20 is arranged in each of the two channels 10, 11, which is acted upon by a spring 21 or the like and the strand 5, 7 in the direction Imposition chamber 9 presses. Both channels 10, 11 have the same width, but is the upper channel 11 is designed to be higher in height than the lower 10.

This magazine 10, 11 is attached to the underside of the housing 8, and although through the upper profile 12, which on the one hand on a pulled down extension 22 of a handle 23 and on the other hand attached to the front guide head 18 is.

In a arranged above the guide head 18 th housing part 24 is a striking piece (not shown) that can be blown away by a pressure medium slidably mounted, which of the two strand gene 5.7 each have a part 2.3 and the two parts 2, 3 together from the guide head 18 out to the Attachment surface attaches.

The handle 23 has an actuating part 25 for the pressure jacket control and thus hammer movement and is further provided with a connection 26 for the Pressure medium line 27 is provided.

The procedure for connecting the cable clamps and the method of operation of the device are as follows: The two receiving channels 10, 11 are moved by moving the slide 14 and the lower profile 13 open against the guide head 18, so that a strand 5, 7 can be inserted into each channel 10, 11. Then takes place the closing of the channels 10, 11 by moving the two parts 13, 14 to the guide head 18 to be pushed back.

Now the hand-held device, which is designed in the form of a shooting pistol, can be used is, with its guide piece 19 over the electrical line 1 to be fastened are set and then via the actuating part 25, the hammer with pressure medium acted upon, which now first detaches a chamber part 3 from the upper strand 7 and transversely to the longitudinal direction of the strand in the imposition space 9 via an underlying fixing part 2 moves, the fixing part 2 also being separated from its strand 5. Both parts 2, 3 are then joined together by the clamp part 3 over the fixing part 2 takes effect. Now both parts 2, 3 are further transverse to the previous one by the hammer Strand feed direction in the imposition space 9 is moved down to the guide piece 19 and shot out of the imposition space 9.

The fixing part 2 and the clamp part 3 are thereby via the electrical Line 1 inserted and the chamber part 3 with its longer U-legs in the mounting surface struck.

After completing this process, the hammer goes up in its starting position back and over the sliding pieces 20 are both strands 5, 7 has been pushed so far into the imposition space 9 that the following Imposition process each a clamp part 3 and a fixing part 2 detected by the hammer and can be separated from strand 5, 7.
