Beschreibung
Zusammenfassung:	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.
