Abstract

A flexible line trimmer head has a housing with first and second parts and a spool for a supply of line. The first and second housing parts are configured to be moved from a spaced relationship towards each other along an operating axis whereupon cooperating connectors engage to block movement of the first and second housing parts away from each other along the axis. The cooperating connectors are provided in pairs at at least three different locations each spaced radially from the operating axis and in a circumferential direction from the other locations.
