A device for opening and closing curtains includes a curtain rail with at least one channel open in the curtain-to-be-hung direction and at least one curtain holding part held movably in the channel in the channel longitudinal direction by guides, for attaching the curtain. The guides are adjustable along the rail via an electric motor drive by a drive mechanism. A laterally-arranged, window-like opening is made in at least one section of the rail profile cross-section, which provides access from outside the rail at least to the channel for the drive mechanism. A structural unit for the electromotive drive and/or a deflection of the drive mechanism is insertable into this opening and fixable therein laterally on the rail for passing the drive mechanism through the region for the electromotive drive and/or the deflection. Also, a method connects an electromotive drive and/or a deflection to the rail profile cross-section.

A connecting rod piece includes a hollow first connecting rod unit, a connecting device, a hollow second connecting rod unit, a first locking member and a second locking member. A side wall of the first connecting rod unit is provided with a first mounting slot. The connecting device has a first end and a second end. A side wall of the second connecting rod unit is provided with a second mounting slot. The first locking member detachably locks the first end of the connecting device to the first connecting rod unit. The second locking member detachably locks the second end of the connecting device to the second connecting rod unit. When the connecting rod piece needs to be mounted, the first connecting rod unit and the second connecting rod unit can be combined into a whole through the connecting device.
