A flexible tubular pipe, in particular for conveying pressurised fluids, comprising pressure-resistant armouring made by winding at least one pair of interlocking metal shaped-section wires of which one has a T-shaped cross-section while the other has a U-shaped cross-section. Ribs on the T-shaped wire extend outwards relative to the flexible tubular pipe, and ribs on the U-shaped wire extend towards the axis of said flexible tubular pipe. The cross-sectional area of the T-shaped wire (3) is substantially larger than the cross-sectional area of the U-shaped wire (4) and, in each side interlocking region consisting of a side rib (13) on the U-shaped wire (4) engaging a side groove in the T-shaped wire (3), and a side groove (9) in the T-shaped wire (3) facing the base portion (12) of the U-shaped wire, as well as between the two ribs (13) of said U-shaped wire, contact is established between the side rib of a first one of the two wires and the second wire, and radial clearance is provided between the side rib of the second wire and the first wire.
