• a groove 40 is used to attach (using a collar) the original handbrake lining.
• the driver of the vehicle wishes to release the handbrake, he actuates the barrel 10 with his key and thus allows the rotation of the latch 22, and releases the protuberance 22-1 from its housing 28. In the unlocked position, the protuberance 22-1 is then placed in the groove 30. The depression of the barrel 10 is therefore possible since the latch 22 can move in the groove 30. The depression of the barrel 10 causes the depression of the release button 34 and therefore the release of the hand brake.
• the two parts 16 and 26 of the cylinder of the device are initially distinct so as to be able to mount the body of the barrel 14 provided with its latch 22 in its place. Once this assembly has been carried out, the assembly of the two cylinder parts is made by a weld bead on the entire circumference of their junction 42.

• the barrel can then be depressed and cause the release of the release button 34 so as to release the handbrake.
• the anti-theft device illustrated in FIGS. 1 and 3 is effective against theft of the vehicle with which it equips the handbrake, it is still possible, coming from an experienced thief, to pierce the barrel of the device to reach the button. release and release the handbrake.
• the axis of the barrel 42 is offset relative to the axis of the handbrake.
• the closing latch 22 In the locked position, the closing latch 22 has its protuberance 22-1 in the housing 28 formed in the body 36 of the device (which is no longer a cylinder as in Figure 1).
• the latch protrusion 22-1 In the unlocked position, the latch protrusion 22-1 is in the low position as illustrated in the figure, and is therefore no longer blocked.
• the depression of the barrel 10 then causes the displacement of the latch 22 which comes to bear on the release button 34 of the handbrake and the depression of the release button 44 enabling the handbrake to be released.
• the assembly of the device of Figure 5 on a hand brake is done without problem, in the same simple way as the assembly of the device of Figure 1, by gluing and screw turning, without requiring a specialist.
• the release button is assembled on the handbrake body by a threaded rod 48 shown in dotted lines in FIG. 6.
• the conventional release button is replaced by a button comprising a groove 52.
• the anti-theft device illustrated in section in FIG. 6 consists of a cylinder fitting onto the handbrake as in the previous embodiments, provided with a part 56 perpendicular to the of the handbrake.
• the part 56 comprises a barrel 58 actuated by a key.
• the barrel has at its end, a bolt 60 which, when the barrel is pressed in the closed position by operating the key, enters the groove 52 of the release button 50. In this position, it is therefore impossible to cause the depression button 50 to enable the handbrake to be released.
• Figure 7 shows the anti-theft device according to the embodiment of Figure 6 when mounted on the handbrake. It can be seen that even if there is little space between the end of the release button 50 and the linings or the gear lever, the anti-theft device does not provide any additional space hindering the operation of the handbrake.
• the barrel 58 and its key being placed upwards, it is extremely easy to carry out the manipulation of the handbrake. Mounting the anti-theft device on the vehicle's handbrake is very easy without the need for a specialist.
• the body or cylinder 54 of the device is fitted onto the hand brake 62 after the latter and the interior of the cylinder have been covered with glue. This adhesive must be very strong in order to resist any attempt to separate the anti-theft device from the handbrake.
• the hand brakes mounted on commercial motor cars are of two types, once the lining, generally made of plastic, has been removed.
• the handbrake body In a first type, the handbrake body has a circular section with a diameter of 20.2 mm.
