A wound closure device (1), in particular a surgical suture (1), comprises- an elongated body (2) having a cross-sectional area with diameter D, and- projections protruding from said elongated body (2),wherein- each of said projections is in the shape of a fin-like angular anchoring element (3, 3') having a lower base part (4, 4') with a base length L, an upper top part (5, 5'), and a height H,- said anchoring elements (3, 3') are arranged in longitudinal direction along the length of the elongated body (2) one after the other in at least two rows (6, 7), with a distance G between any two anchoring elements (3, 3') in any row (6, 7),- each of said anchoring elements (3) in a row (6) is aligned relating to each corresponding anchoring element (3') of any other row (7), and- each section (8) of the elongated body (2) between two successive anchoring elements (3) in a row (6) has the same tapered shape in longitudinal direction, with a steady change or an essentially steady change in the cross-sectional area of the elongated body (2).
