Claim:
1. A extensible and retractable, helically reinforced hose, comprising: a) a continuous axially extending helix of extruded thermoplastic material having a uniform cross-section along its length forming axially spaced reinforcing coils of the hose; b) a continuous web of extruded thermoplastic material of substantially uniform width and relatively thin cross-section continuously bridging between and continuously connected to an adjacent pair of the reinforcing coils forming a continuous, helically extending sidewall of the hose; c) with the web having opposed, substantially spaced edge regions, one of which is bonded continuously to a radially outwardly facing bonding surface provided by an outer diameter region of one of the adjacent reinforcing coils, and the other of which is bonded continuously to a radially inwardly facing bonding surface provided by an inner diameter region of the other of the adjacent reinforcing coils; and d) with the two spaced edge regions of the web continuously radially separated from each other by the axially extending helix continuously interposed therebetween.
