The metal corner piece has clips which fit in a channel (24) on the aluminium extrusion.

The aluminium extrusion (20) carries flanges (26) directed towards but stopping short of the sharp corner.

In an expansion joint structure according to the invention the profile elements and connecting strips constitute a single continuous entity of extruded aluminium profile.

Available both in the horizontal and the vertical version, it comprises an extruded aluminium profile with a T-shaped section, after which it is named.

Preferably, the extruded profile consists of aluminum or an aluminum alloy.

According to the invention, the holder (2) takes the form of a short, truncated piece of an extruded section, preferably an extruded aluminium section.

The metal corner piece has clips which fit in a channel (24) on the aluminium extrusion.

Each door panel comprises an extruded metal section (18), and the part (14) is also an extruded metal section.

According to the invention, said vehicle reinforcement component (5, 7, 17, 18, 22) is made from a pultrusion profile and in particular, from a curved pultrusion profile or radius pultrusion profile.

The exchanger pipe (4) is formed as an extruded section from an aluminium-based alloy.

The aluminium extrusion (20) carries flanges (26) directed towards but stopping short of the sharp corner.
