Abstract: A window wiper device (1, 20, 40, 100) having a pantographic arm (22) at the end of which a main wiper blade is attached. A secondary wiper blade (101), placed beneath the main wiper blade (32), is mounted on the pantographic arm (22) by means of a pantographic device that is intended to offset the secondary wiper blade (101) from the main wiper blade (32), such that the two wiper blades (32, 101) can perform their wiper functions continuously on the window (10).

Abstract: A male connector is disclosed having an adjustable diameter for insertion in a socket. The connector includes an internal sleeve having a rotary sleeve. An external sleeve partially surrounds the internal sleeve and the rotary sleeve. A finger is attached to the external sleeve. In response to a rotation of the rotary sleeve, the finger moves laterally to change the connector diameter. Both the finger and the rotary sleeve do not move longitudinally. The connector further includes a locking device to maintain the rotary sleeve in a desired position. The locking device has a first series of teeth along an outer surface of the internal sleeve for cooperating with a second series of teeth along an inner surface of the external sleeve. In addition, the connector includes a cam having a profile which allows the diameter to change when the finger follows the cam profile in response to the rotation of the rotary sleeve.
