ABSTRACT:
A handle (1) for use on a bucket of plastic material and a fastening knob (2) are integrally moulded and interconnected by a moulded fin (4). The fastening knob (2) has a head (5), an elastically resilient flange (6) slanting outwards, and a shank (7). When the handle is to be attached to a bucket, the free end of shank (7) is connected to the bucket wall, preferably by ultrasonic welding, and handle (1) is pressed towards the wall. Head (5) is pressed through an aperture (3) in the handle to pivotably mount the handle on the shank (7), with flange (6) acting as a barb-like anchoring member preventing the handle from falling off. Simultaneous moulding of the handle and the fastening knob renders the use of lateral core removing openings superfluous and simplifies mounting of the handle and the knob.
