ABSTRACT:
An external hose coupling member is adapted with a pair of pulling ears which when subjected to forces exceeding a predetermined threshold for the particular hose, will disengage the pulling chains and save the hose from damage. The ears are adapted to rotate from a pull engaging position to a disengaging position by means of shear pins that will hold the engaging position until the predetermined threshold for the hose is reached whereupon the pins will shear and rotate to their disengaging positions.
