A reinforced medico-surgical tube comprises a tube (9) of flexible material, a filament helix (15) coaxial with the tube (9) and disposed between inner and outer peripheries of the tube (9), and a distal end (10) of the tube, the distal end (10) including a straight-cut or angle-cut axial end face disposed at an angle equal to or other than 90 DEG with respect to a central axis of the tube (9). The filament helix (15) is separated into pieces at the distal end (10) if the tube (9) is angle-cut such that coils of the filament helix (15) are discontinuous with opposite ends of the coils adjacent the end face of the distal end (10). The cut filament end in the case of a straight-cut tube or the cut filament ends in the case of an angle-cut tube confront the axial end face and are separated therefrom by a thin layer of flexible material formed by melting the end face, melting a plastic piece (18) onto the end face or by any other suitable method. <IMAGE> |
