The instant invention is a low cost hose guide consisting of a one-piece spike having a first pointed end and a second flat surface available for tapping the pointed end into the ground. The spike includes locking tabs for placement of a single piece roller that is engaged in an area above the locking tabs and below the second surface and is rotatable around the spike. Once the hose guide is positioned into the ground a hose may be dragged around the hose guide wherein the hose guide maintains the hose in a guided fashion so as to prevent damage to critical areas such as flower beds and infant vegetation.

Why it's free to use
- Filed June 5, 1996 and granted April 27, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 5, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 5, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
