Definitions

• the invention relates to is a tubular handle for an element closing an object opening, in particular for a door or window wing, comprising a tubular handrail connected to at least one fixing element, an optional masking element in which the fixing element is disposed, and a control cable connecting a first control component disposed in the handrail with a second control component disposed in the closing element or in the object.
• the object of the invention was to provide a tubular handle with a simple and aesthetic structure facilitating access to the control cable when the handrail is disconnected from the fixing element.

• the relatively large surface of said blanking flap allows use and access to large couplings joining sections of the control cable.
• ..control cable denotes a tensile force transmitting element that may be used for transmitting information between components disposed at its ends, and in particular single or multi-core electrical cable, optical fiber, liquid or gas- filled tube, line, etc.
• the term also refers to a control cable having two sections consisting of a first control cable located in a tubular handrail detachably connected to a second control cable, the end of which exits the fixing element.

• Metal connecting element 64 is soldered to the blanking flap 61a, which passes through a connection hole 633 in the wall of the shaped element 63a and is provided with a bent section 641 that prevents removal of the blanking flap 61a from the z blanking mechanism 6a without an additional force. Furthermore, such a shaping of the connecting element 64 and the bent section 641 ensures that in its neutral position (Fig. 3) the blanking flap 61a is slightly tilted from the access opening 62a, which facilitates its manual further deflection to the uncovered position in order to gain access to a coupling 511 of the section of the first control component 51 of the control cable 5.
