A flexible hose having an inner tube member made from a thermoplastic elastomer material and an outer tube member made from a non-elastic polyester material. The inner tube member is secured to the outer tube member only at an inlet coupler and an outlet coupler. The inlet coupler is constructed to secure to a water supply provided from a conventional household water spigot. The outlet coupler incorporates a flow restrictor allowing the inner tube member to equalize in pressure with pressurized water received from the water supply. Pressurized water expands the elongated inner tube member longitudinally along a length of the inner tube member and laterally across a width of the inner tube member thereby substantially increasing the length of the hose to an expanded condition wherein the hose contracts to a substantially decreased length when there is a decrease in pressurized water.

The hose of claim 1 wherein said inlet flow thru aperture is partially hex shaped for receipt of a similar shaped tool for use in assembly of the first collar member. 13. The hose of claim 1 wherein said outlet flow thru aperture is partially hex shaped for receipt of a similar shaped tool ease of assembly of the second collar member. 14. The hose of claim 1 including indicia on said outer tube member. 15. A hose for water comprising: a flexible non-elastic elongated outer tube having a first end and a second end, an interior of said outer tube being substantially hollow;a flexible elastic elongated inner tube having a first end and a second end, an interior of said inner tube being substantially hollow;a female coupler including a tubular extension which extends into the interior of the first end of said inner tube, the extension having a hollow interior through which water can flow; and a first securing device encompassing said first end of said inner and said outer tubes securing said first end of said inner and outer tubes to said female coupler tubular extension;a male coupler including a tubular extension which extends into the interior of the inner tube, the extension having a hollow interior through which water can flow; and a second securing device encompassing said second end of said inner and said outer tubes securing said second end of said inner and outer tubes to said male coupler tubular extension;said inner and outer tubes being unattached, unbonded, unconnected and unsecured to each other except at the couplers;said female coupler coupling said hose to a source of pressurized water, said male coupler coupling said hose to a water flow restrictor;whereby, when water under pressure is introduced into the female coupler, said elongated inner tube expands longitudinally along a length of said inner tube and laterally across a width of said inner tube thereby increasing a length of said hose to an expanded condition; andwherein the water flow restrictor is configured to vary the amount of restriction of the water under pressure that is released from the hose while maintaining the length of the hose in the expanded condition. 16.
