Abstract: A handle piece (15) for application to the cross bar handle (14) of a domestic hose cock comprises a unitary plastics moulding comprising an open bottomed shell (16) having an upper surface sized to fit into the palm of the hand. Formations within the shell define a recess adapted to receive the cross bar handle and comprise opposed pressure pads (19,20) at or near each end of the recess adapted to bear against respective end portions of a cross bar handle when homed in said recess. Two opposed resilient flanges (22) resiliently clasp the cross bar handle intermediate its ends to retain the handle piece in position upon and shrouding the cross bar handle.
