An elongate carrying strap reinforced by longitudinally extending multi-strand wire cables (41) is engaged with a fitting (1) for forming a loop (64) at an end of the strap (2) so as to avoid inelastic deformation of the cable. A pair of multi-strand wire cables are received in parallel envelopes (43) disposed on opposite longitudinal edges of the strap, each envelope is tubular and formed in a flexible polymer strip (40) extruded over the cable. The fitting has a transverse bar portion (71) having a convex face abutting the inner side of the loop and a pair of transverse arm portions (9, 10) defining an opening therebetween, the opening receiving a neck (63) of the loop and having opposing strap-engaging surfaces abutting the outer side of the strap and cooperating to hold the inner side against the convex face (4) of the bar portion (71).
