1. A wire tensioning device comprising:
at least one wire tensioning member, formed as a bent metal fork having a first end as a bridge connected to a second end by two longitudinal arms, the second end having two free ends, and the at least one wire tensioning member being formed of a rod having a circular cross-section;
a support member adapted to support the tensioning member in rotation, the support member having at least one through-hole; and
blocking means to block the rotation of the tensioning member, the blocking means being a cam-shaped portion of the at least one through-hole, wherein
the arms of the tensioning member penetrate the at least one through-hole so that the tensioning member rotates independently with respect to the support member to tension a wire, and the tensioning member reversibly engages with the cam-shaped portion,
the support member and the blocking means are formed integrally,
the arms extend from undercut portions positioned between the first end and the arms, the undercut portions extending in a direction toward each other, and the two free ends bending in a direction away from each other, and
the cam-shaped portion is arranged to receive the undercut portions to block the rotation of the tensioning member.
