A device for winding a flexible tube, the device including two identical blades LA placed opposite ways round one against the other and pivotally secured to each other about their respective axes of axial symmetry, which together constitute a pivot axis PIV. One of the blades presents in its left edge an upwardly open notch EC that is formed by a first circular arc ARC1 having its origin at a connection point PR situated on the right edge of the notch and on the longitudinal axis LG of the blade; a diameter of the first circular arc lying on the longitudinal axis; and the first circular arc presenting a central angle α of not less than 180°.

A rope clasp device for securing a rope eliminates the need for a knot in a rope by selectively clasping and encasing at least one portion of a rope in a toothed clamp. The rope clasp device comprises a base, at least one, but generally two swinging doors, and a lock. The swinging doors are pivotably coupled to the base in order to be moved between an open position and a closed position. In the closed position, a pair of channels for passage of a rope is defined between the base and the doors. The channels are defined by a plurality of clasping teeth to retain the rope therein.

The invention provides a device for winding a flexible tube, the device comprising two identical blades LA placed opposite ways round one against the other and pivotally secured to each other about their respective axes of axial symmetry, which together constitute a pivot axis PIV.

The device is remarkable in that: one of the blades presents in its left edge an upwardly open notch EC that is formed by a first circular arc ARC1 having its origin at a connection point PR situated on the right edge of the notch and on the longitudinal axis LG of the blade; a diameter of the first circular arc lying on the longitudinal axis; and the first circular arc presenting a central angle of not less than 180.

A hold down device is provided for continuous loop cords or bead chains in a window covering installation. The hold down device engages the cord or chain while the cord or chain is loosely suspended, and prevents operation by encountering the head rail if the cord or chain is operated. Mounting the hold down device in a window covering installation disengages the hold down device from its secured position relative to the cord or chain.
