1. A windscreen wiper device comprising:
a connecting device; and
a joint part detachably and pivotably connected to said connecting device about a pivot axis;
said joint part comprising at least one resilient tongue engaging in a correspondingly shaped hole provided in an oscillating arm wherein said at least one resilient tongue is rotatable along an hinge axis between an outward position and an inward position,
wherein:
said oscillating arm has an at least substantially U-shaped cross-section at a location of its connection to said joint part,
at least one leg of said U-shaped cross-section of said oscillating arm comprises an outer surface, an inner surface, a first end, and a second end, the first end of the at least one leg abutting a top surface of the oscillating arm, the second end of the at least one leg positioned opposite the first end,
an inwardly extending protrusion is positioned on the inner surface of the at least one leg and spaced between and apart from the first end of the at least one leg and the second end of the at least one leg, the protrusion cooperating with a bottom surface of a side wall of said joint part near an extremity of said joint part facing away from a free end of said oscillating arm,
the bottom surface comprises an elevated portion and a lower portion, the elevated portion and the lower portion define a stepped profile,
a sloping section is arranged at an end of the joint part adjacent the extremity of the joint part, the sloping section comprising a portion of a dimple that tapers towards the elevated portion of the stepped profile to guide the inwardly extending protrusion,
said protrusion cooperates with the elevated portion of said bottom surface of said side wall of said joint part,
said joint part and said oscillating arm are assembled by a linear movement of said joint part towards said oscillating arm in a longitudinal direction parallel to a longitudinal axis of said oscillating arm until said resilient tongue engages inside said hole provided in said oscillating arm, and
said joint part is detachably attached to said connecting device by pivotally engaging projections of said connecting device, at the location of said pivot axis, in recesses provided in said joint part.
