Abstract: A curtain rod structure provides both telescopic adjustment and a mechanism by which multiple curtain rods can be efficiently attached together. In at least one aspect, a curtain rod assembly includes: a rod member of a first type, wherein the rod member of the first type includes a connector element that attaches with an end-piece associated with the curtain rod assembly; a rod member of a second type, which is different than the first type, wherein the rod member of the second type connects with the rod member of the first type in a telescopic manner; and a fastener that attaches at either end to the connector element of the rod member of the first type; wherein the fastener has an associated stop mechanism to retain the fastener at a defined position when attached to the connector element.
