The windscreen wiper device includes a wiper blade that is made of an elastomeric material and extends in a longitudinal direction. The windscreen wiper device also includes a joint part with a U-shaped cross-section that includes a top wall and a pair of side walls. At least one of the side walls has a spring loaded interference finger which projects outwardly for engaging an inner surface of a wiper arm to reduce side to side play between the joint part and the wiper arm.
