ABSTRACT:
A flexible spiral spring insert for a hose end segment is disclosed which insert includes an enlarged end portion for retentive engagement with a coupling component on the hose end. The enlarged end portion may be a ring-shaped retainer chamferred about its outer periphery to avoid interference with seating of a nozzle rim with the washer of the coupling assembly. A modified form of the invention discloses an enlarged conical extension formed on one end of the flexible spiral spring insert while a still further modification includes a radially enlarged end coil of the insert with the coil adapted for washer engagement. The washer may be modified to be internally recessed to receive a radially expanded end coil of the spring to confine the spring against axial displacement.
