Abstract
A safety lock for a hose coupling is disclosed. The safety lock has a substantially L-shaped lever having a longer upper leg and a shorter lower leg pivotable about a solid post extending from and integral with the coupling. The lever is positioned adjacent a support surface of the coupling, such that the shorter lower leg is within a distance of 0.05 inches or less to the support surface. The safety lock may be formed of a polymer or any material, which when conditioned to a relative humidity of 50% and tested at a temperature of 73° F., has an elongation at yield of at least 10% and a flexural modulus of at least 100,000 psi.

A safety lock for a water hose coupling, the water hose coupling being made of a metal, the safety lock being formed of a polymeric material.
A device for preventing accidental releasing rotation of one elongated conduit with another elongated conduit, wherein the conduit ends are aligned and connected to one another with a first and a second coupling, the first and second couplings together creating a water-tight seal, and wherein the first coupling comprises:
- a solid post extending from and integral with the coupling, the coupling being made of a metal;
- a support surface;
- and,
- a polymeric, substantially L-shaped lever positioned adjacent the support surface, and pivotable about the solid post.
