Windscreen wiper device

A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible elastomeric rubber material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes opposing longitudinal grooves on its longitudinal sides, in which grooves spaced-apart longitudinal strips of the carrier element are disposed, wherein ends of said wiper blade are connected to a respective connecting piece, which windscreen wiper device comprises a connecting device for an oscillating wiper arm, wherein at least one connecting piece comprises retaining members in the form of at least one pair of sidewardly extending gripping teeth each in the shape of a hook for gripping into an intermediate web of said wiper blade as defined by opposing longitudinal slits of said wiper blade, and wherein said gripping teeth only slightly penetrate the elastomeric rubber material of said wiper blade without damaging said web, and wherein neighboring ends of said longitudinal strips are interconnected by said respective connecting pieces, and wherein engaging members of said connecting pieces engage around said longitudinal strips so that said strips are mounted in grooves formed by said engaging members and wherein one of said connecting pieces at one end of the wiper blade is closed and includes an end wall in order to block a relative movement of the wiper blade along said longitudinal strips inside said connecting piece in a direction towards said connecting piece during use, and wherein the other of said connecting pieces at the opposite end of said wiper blade includes an opening at its free end.
