Lamp for motor vehicles

1. An arrangement for releasably securing a lamp assembly to a motor vehicle comprising:

a first fixing member cooperating with an inner face of a housing of the lamp assembly; and

a second fixing member including first interlocking part securable to the motor vehicle and a second interlocking part securable to the housing of the lamp assembly, the first and second interlocking parts each having proximal and distal ends, the second interlocking part configured to releasably engage the first interlocking part at both the proximal and distal ends thereof to secure the lamp assembly to the motor vehicle, wherein the first interlocking part includes a locating tongue at the proximal end and a cross beam incorporating a ridge at the distal end, and wherein the second interlocking part includes a lip at the proximal end to engage the locating tongue of the first interlocking part and a ridge at the distal end to engage the ridge of the first interlocking part.

2. The arrangement of claim 1 wherein the first and second fixing members are located at proximate opposite ends of the housing.

3. The arrangement of claim 1 wherein said first and second fixing members each incorporate threaded bolts.

4. The arrangement of claim 1 wherein the second interlocking part of the second fixing member is formed as part of the housing.

5. A lamp assembly for a motor vehicle, the lamp assembly comprising an elongate trough-shaped housing for containing at least one light source and being closed by a covering pane and including first and second fixing means, located proximate opposite ends of said housing respectively, for releasably securing the lamp to the vehicle, wherein said second fixing means comprises two interlocking parts, detachable from one another, the two interlocking parts comprising a first interlocking part and a second interlocking part each having proximal and distal ends, wherein the first and second interlocking parts mechanically attach to each other at both the proximal and distal ends, wherein the first interlocking part includes a locating tongue at the proximal end and a cross beam incorporating a ridge at the distal end, and wherein the second interlocking part includes a lip at the proximal end to engage the locating tongue of the first interlocking part and a ridge at the distal end to engage the ridge of the first interlocking part.

6. The lamp assembly of claim 5 wherein the interlocking, detachable parts include a snap fastening arrangement.

7. The lamp assembly of claim 5 wherein the interlocking, detachable parts are made from plastics.

8. The lamp assembly of claim 5 wherein said first and second fixing means incorporate threaded bolts.

9. The lamp assembly of claim 5 wherein the second interlocking part is formed as part of the housing.

10. A lamp assembly for a motor vehicle comprising:

a housing having an inner face and an outer face;

at least one light source received within the inner face of the housing;

a first fixing arrangement cooperating with the inner face of the housing for securement to a surface of the motor vehicle for releasably securing the lamp assembly to the motor vehicle: and

a second fixing arrangement cooperating with the inner face of the housing for securement to the surface of the motor vehicle,

wherein the second fixing arrangement includes a first interlocking part securable to the motor vehicle and a second interlocking part securable to the housing, the first and second interlocking parts each having proximal and distal ends, wherein the first and second interlocking parts releasably engage each other at both the proximal and distal ends thereof to secure the lamp assembly to the motor vehicle, wherein the first interlocking part includes a locating tongue at the proximal end and a cross beam incorporating a ridge at the distal end, and wherein the second interlocking part includes a lip at the proximal end to engage the locating tongue of the first interlocking part and a ridge at the distal end to engage the ridge of the first interlocking part.

11. The lamp assembly of claim 10 wherein the housing is formed as an elongate trough-shaped member.

12. The lamp assembly of claim 10 further comprising a covering pane configurable to be secured to the outer face of the housing.

13. The lamp assembly of claim 10 wherein the first and second fixing arrangements are located at proximate opposite ends of the housing.

14. The lamp assembly of claim 10 wherein the first and second interlocking parts of the second fixing arrangement are securable by a snap fastening arrangement.

15. The lamp assembly of claim 10 wherein the first and second interlocking parts of the second fixing arrangement are made from plastics.

16. The lamp assembly of claim 10 wherein said first and second fixing arrangements each incorporate threaded bolts.

17. The lamp assembly of claim 10 wherein the second interlocking part of the second fixing arrangement is formed as part of the housing.
