1. For use in a swimming pool, a hose assembly comprising:
- an elongated resiliently flexible hose having alternating relatively long ribbed portions and relatively short smooth portions with respect to each other along the longitudinal length thereof, each of the ribbed portions comprising a series of alternating ribs and grooves extending around the circumference of the hose and each of the smooth portions having an outer diameter substantially smaller than the outer diameter of the ribs of the ribbed portions;
at least one attachment removeably mounted on said hose around one of said smooth portions in a position longitudinally between an adjacent pair of said ribbed portions, said attachment having a generally hollow cylindrical body having a length no longer than the length of said one of said smooth portions and being divided longitudinally along one side to form a slot extending the full length of the body, said body having an inside diameter smaller than the outer diameter of the ribs of said adjacent pair of said ribbed portions so that the ribs of said adjacent pair of ribbed portions longitudinally retain the attachment on the hose about said one of said smooth portions, said body being composed of resiliently flexible material to permit opening of said slot for assembly of the attachment on the hose; and
said body being a non-buoyant sleeve having a plurality of outwardly projecting fin members each having a wheel rotatably mounted thereon.

Abstract
A flexible hose has ribbed portions concatenated with cylindrical smooth tions. The ribbed portions provide flexibility and resilience to the hose. Flotation cuffs for buoyancy and wheel cage cuffs for reducing friction are mounted on selected smooth portons of the hose. A fitting removeably attaches to a ribbed portion forming the end of the hose to allow rotatable attachment of the hose to other apparatus.

6. For use in a swimming pool, a hose assembly comprising:
-
an elongated hose composed of resiliently flexible material, said hose having alternating, relatively long ribbed portions and relatively short smooth portions with respect to each other along the longitudinal length thereof and having a ribbed portion at one end, each of the ribbed portions comprising a series of alternating ribs and grooves extending around the circumference of the hose and each of the smooth portions having an outer diameter substantially smaller than the outer diameter of the ribs of the ribbed portions; a fitting mounted on said one end of said hose, said fitting having an opening for receiving said one end and at least one of said ribs with a close fit, and internal abutment means on said fitting in said opening for extending into a groove alongside one of said ribs and interlocking with the rib, said hose being insertable in said opening in collapsed condition and expandable into interlocked relation with said abutment means; and at least one attachment removeably mounted on said hose around one of said smooth portions in a position longitudinally between an adjacent pair of said ribbed portions, said attachment having a generally hollow cylindrical body having a length no longer than the length of said one of said smooth portions, and said attachment being divided longitudinally along one side to form a slot extending the full length of the body, said body having an inside diameter smaller than the outer diameter of the ribs of said adjacent pair of said ribbed portions so that the ribs of said adjacent pair of ribbed portions longitudinally retain the attachment on the hose about said one of said smooth portions and being composed of said resiliently flexible material to permit opening of said slot for assembly of the attachment on the hose. - View Dependent Claims (7, 8, 9, 10, 11)
