The recess (6) is defined in part by arcuate profiles (8) on mutually facing, inner surfaces (9) of each arm (10) of the 'V' or 'U', which arms (10) are adapted to splay apart resiliently during the fitting and the removal of a clip on the water spray nozzle (2), whilst a portion of the clip (1) is provided with a clip retraction surface (12). The invention also includes a water spray nozzle (2), a pick box (4), and a rotary mineral cutting head (36).
