Holonomy and loop variables are presented for the spacetime of a
torsion line defect in 
-dimensional spacetime
immersed on a 
-dimensional spacetime. The metric
considered has a teleparallel counterpart presented earlier by
Letelier (Class. Quantum Grav. (1995)). In this letter
we show that the -dimensional torsion defect given by
Letelier metric does not appear only in teleparallel
(Weitzenböck) spacetime, but also in Riemann-Cartan (RC)
spacetime. Since here the space off the torsion defect is not
teleparallel, torsion appears only through curvature effects and
maybe detected off the torsion lines.
