Seal

A lock comprising a housing (5) and a strap (1) that has a first end (2) and a second end (6), said housing (5) comprising:

• means for securing the first end (2) of the strap (1);
• an interior cavity (40);
• a first (7) and a second (8) opening allowing advancement through the housing (5) of the second end (6) of the strap (1);
• a first interior, longitudinally extending wall (9) and a second opposed, interior, longitudinally extending wall (10), said walls extending between said first and second openings;
• a locking device (14) arranged within the cavity (40) between the first wall (9) and the second wall (10) and that defines a nipping area (45) for securing the second eng(6) of the strap (1);
• and
• support areas (50) for the strap (1) whereby rotation of the strap (1) about its longitudinal axis is prevented,
• characterized in that the strap (1) is a string of a plastics material (110) having a polygonal cross section and cooperating with said support areas (50) for preventing said rotation, said string of plastics material (110) being internally reinforced by a wire formed by twisted metal wires,
• that the strap (1) is manufactured by extrusion, and
• that the locking device (14) is a substantially circular metal disc or roller with a rough or toothed surface arranged along the circle periphery.
