• a three-separate-part securing system comprising a retaining plate and two cooperating clamping angles;
• the retaining plate comprises at least one horizontal guide channel for the first and second clamping angles;
• wherein the two cooperating clamping angles comprise a first clamping angle and a second clamping angle, the first and second clamping angles are arranged on the retaining plate such that each of the first and second clamping angles being configured to be shifted in relation to the retaining plate and thereby change a span width of the first and second clamping angles;
• wherein the two cooperating clamping angles are arranged on the retaining plate in a rotationally fixed manner;
• each of the two cooperating clamping angles comprises at least one planar clamp and at least one connector, the at least one connector configured to be guided within the horizontal guide channel;
• the first clamping angle comprises at least one female thread each configured to receive a respective positioner;
• the second clamping angle comprises at least one connecting hole corresponding respectively to the at least one female thread;
• wherein the retaining plate of the three-separate-part securing system is configured to be secured to a part of the door frame;
