A skate for a flexible cable guide comprises a series of interconnected skate units, each comprising a pair of parallel rails with rollers, the rails being connected by transverse connecting bars. A connecting block is provided with two holes. A connecting bar of one of skate units extends through one of the two holes. The other hole has a longitudinal entry slot for receiving a narrowed portion of a bar of the other skate unit. The narrowed portion is formed by providing one or more flat portions on the bar, disposed at a 45° angle with respect to the longitudinal direction of the skate, in order to require manipulation of the connecting block for engagement and disengagement of the bar having a narrowed portion from the connecting block.
