Wire base body with reinforced exterior

The body (1) has a filament (2) extending in a meander-shaped inlet along a longitudinal axis. The filament is bent around a bending axis that is parallel to the longitudinal axis, and includes perpendicularly crossed and compression-proof traction mechanisms (5) that are defined relative to each other. The traction mechanisms are attached to an external end of the inlet and the filament, so that deformation of the body is prevented in the region of the traction mechanisms around a uniform axis (8) transverse to the bending axis during bending of the body.
