2. The device as claimed in claim 1 , wherein said alarm-generating device comprises an antenna ( 8 b ) and a radio transmitter for sending alarm messages on a communication network accessible from a user's client.

3. The device as claimed in claim 1 , wherein said auxiliary anti-intrusion body ( 6 ) is arranged on one side of the anti-intrusion containment body ( 4 ) towards which said plug means extend in the constraint component ( 1 ).

4. The device as claimed in claim 3 , wherein said auxiliary anti-intrusion body ( 6 ) is in the form of a C-shaped profile, fastened along one side of said anti-intrusion containment body ( 4 ).

5. The device as claimed in claims 3 , wherein said auxiliary anti-intrusion body ( 6 ) is in the form of a tubular profile with dimensions 30×40×100 mm with a 4-mm thick wall.

6. The device as claimed in claim 1 , wherein said drawer element ( 7 ) has at least one through-aperture ( 7 a ) for one of said plug means ( 1 a ).

7. The device as claimed in claim 1 , wherein said electronic unit ( 8 ) comprises an electronic card ( 8 a ), provided with at least one movement/displacement sensor and with at least one alarm.

8. The device as claimed in claim 7 , wherein said movement/displacement sensor is an accelerometer/inclinometer.

9. The device as claimed in claim 7 , wherein said alarm comprises a sound signaller.

10. The device as claimed in claim 7 , wherein said movement/displacement sensor comprises a geographic positioning device (GPS) and means for associating geographic position data with said alarm.

11. The device as claimed in claim 1 , wherein at least one of said plug means ( 1 a ) of the constraint component ( 1 ) has a permanent magnet ( 10 ).

12. The device as claimed in claim 1 , wherein said constraint component ( 1 ) takes up the shape of a U-shaped fork, or of a flexible chain, or of a disc-locking clamp, or of an immobiliser rod for a motor vehicle.

13. An anti-theft set comprising a device as claimed in claim 1 and a plurality of constraint components ( 1 ) comprising at least a U-shaped fork.

14. The device as claimed in claim 2 , wherein said auxiliary anti-intrusion body ( 6 ) is arranged on one side of the anti-intrusion containment body ( 4 ) towards which said plug means extend in the constraint component ( 1 ).

15. The device as claimed in claims 4 , wherein said auxiliary anti-intrusion body ( 6 ) is in the form of a tubular profile with dimensions 30×40×100 mm with a 4-mm thick wall.

16. The device as claimed in claim 8 , wherein said alarm comprises a sound signaller.

17. An anti-theft device comprising:

a constraint component ( 1 ) comprised at least one plug means ( 1 a );

a locking component ( 2 ) engageable with constraint component ( 1 ),the locking component ( 2 ) comprising an anti-intrusion containment body ( 4 ) housing an operating clamp ( 5 ), said anti-intrusion containment body ( 4 ) having at least one engagement seat ( 3 ) for the at least one plug means ( 1 a ) of said constraint component ( 1 );

an auxiliary anti-intrusion body ( 6 ) associated with said anti-intrusion containment body ( 4 ), said auxiliary anti-intrusion body ( 6 ) having a compartment and at least one through-seat ( 6 a ) for said at least one plug means ( 1 a ) of said constraint component ( 1 ),said anti-intrusion containment body ( 4 ) having a box shape;

a drawer element ( 7 ) insertable into said compartment of said auxiliary anti-intrusion body ( 6 ), said drawer element ( 7 ) comprising at least one electronic unit ( 8 ) provided with an alarm-generating device and at least one of the group consisting of a position detection sensor and an attitude detection sensor, wherein, with the drawer element ( 7 ) in said compartment of said auxiliary anti-intrusion body ( 6 ) and the plug means ( 1 a ) of the constraint component ( 1 ) being engaged with said anti-intrusion containment body ( 4 ), a cage is defined for said drawer element ( 7 ) including the electronic unit ( 8 ) which remains inserted and protected, and wherein said drawer element ( 7 ) has at least one through-aperture ( 7 a ) for one of said at least one plug means ( 1 a ).
