A telescoping, adjustable-length rigid rod for mounting between opposing surfaces, such as the opposing interior walls of a swimming pool, for retaining a cover or the like in position is provided. An elongated tubular structure comprised of a number of telescoping tube sections biased apart by springs forms a rigid rod for compressibly mounting between opposing surfaces. The rod is provided with a locking handle which, in the locked position, expands the telescoping sections lengthwise thus forcing the ends of the rod against the opposing surfaces to prevent removal.
