ABSTRACT:
The invention is directed to a lockable support float, preferably blow molded, for use in swimming pools and the like. It comprises at least first and second expanded members having mateable ends which are adapted to slide over and lock onto a rope. Each member includes an opening that is eccentrically positioned therethrough and alignable with each other for sliding engagement with a rope. Each member includes either a female or a male locking member comprising concentrically positioned annular groove and annular extension, respectively. The annular groove includes at least two projections which extend over a portion of the groove, and the annular extension includes a flange around the perimeter thereof for locking engagement with said projections. By rotation of the locked members the respective openings therethrough become offset with respect to each other and any rope positioned therethrough is securely locked in the openings of the float.
