Abstract
Abstract The invention relates to an arrangement for obtaining an uninterrupted connection of an electric cable or the like between two elements pivotally hinged to each other, in particular, between a door frame element and a door connected thereto. The arrangement comprises, at the position of the connection, a member arranged around the cable in the form of a separate, turnable and longitudinally flexible protecting element. This element is arranged basically in the longitudinal direction of the door frame element and one end of the element is connected to the door frame element and the other end to an adjacent edge part of the door. There is, for said protecting element, in the door frame and/or in said door edge part, at least one recess. This recess is so arranged that, when the door is closed, the protecting element and said cable are received in this recess.
