ABSTRACT:
A securing means for a double step ladder having a U-shaped element, a coupling element, a retaining rod received within the openings provided on the distal ends of the lateral walls of the U-shaped element, a flap fixed on the lateral wall of the U-shaped element to receive the retaining rod, and a cap to engage with the retaining rod. The securing means is mounted on a step ladder, in which the upper and lower legs of the ladder are clamped among the U-shaped element, the coupling element and the retaining rod. The position of the upper and lower legs is adjustable by the engagement of the retaining rod with the cap. The retaining rod has two horizontally protruding plates on both of which a hole is provided to receive a cylindrical pivot piece which has an eccentric protrusion provided on upper and lower surfaces and a cavity provided on a cylindrical surface to receive a pivot rod which is rotatable to cause a radial movement of the pivot piece urging against the U-shaped element.
