ABSTRACT:
A firehose coupling which helps fire fighters determine the direction to safety along a firehose. The preferred embodiment of the firehose coupling incorporates an elongated extension integrally attached to each lug of a male component of the firehose coupling, which extends a predetermined length beyond the perimeter of the cylindrical body of the male component only, in a direction diametrically opposed to the direction by which said male component is inserted to couple with said female component. These extensions are easily identified visually, directing the fire fighter away from the fire and towards the source connection of the firehose. Additionally, the lug extensions may have raised or printed indicia on their surface further assisting a fire fighter. The tactile feature of the extensions are particularly advantageous in low visibility situations for fire fighters wearing heavy gloves, whereby a fire fighter need only momentarily and lightly catch his thumb against the lug extension, and without hesitation know the firehose's water source direction. Any extension or tab which extends beyond the perimeter of the cylindrical body of the male component may be incorporated intermittently along the circumferential edge of the firehose-accepting end of the male component's cylindrical body to form additional embodiments of the invention.
