The fixing element (14) comprises a covering cap (16) and the connection element (22) fixed to the wiper arm (18) secures the wiper blade (10) perpendicularly to a pivoting axis (20) by means of a clip (52), on the end (54) thereof at an angle to the wiper blade. According to the invention, the covering cap (16) comprises an opening (34) or recess for the angular end (54) of the clip (52), on the side of the cap opposing the rubber profiled element (48), in the region of the connection element (22), said opening only partially overlapping the covering cap (16) in the mounted position. ## Claims ### Claim 1 Wiper blade (10), constructed of a rubber profiled element (48) with a wiper lip (50) and at least one support element (46), connectable to a wiper arm (18) by a fixing element (14) and a connection element (22), the fixing element (14) having a covering cap (16), the connection element (22) being fastened to the wiper arm (18) and securing the wiper blade (10) via a clip (52) transverse to a pivoting axis (20) by means of an end (54) of the clip (52) bent towards the wiper blade (10), characterized in that the covering cap (16) defines one of an opening (34) and a recess for the bent end (54) of the clip (52) on a side of the cap (16) facing away from the rubber profiled element (48) in a region of the connection element (22), the clip (52) only partially overlapping the covering cap (16) in a mounted position, characterized in that the connection element (22) has a fastening plate (56) running parallel to a wide side of a wiper rod (18), on which fastening plate the clip (52) is formed, in that the fastening plate (56) is attached on an inner side of an end (26) of the wiper rod (18) and a covering (70) is provided on an opposite side of the end (26), and in that a front wall (72) of the covering (70) covers a front side of the end (26) and of the connection element (22). ### Claim 2 (depends on 1) Wiper blade (10) according to claim 1, characterized in that a covering wall (38) of the covering cap (16) runs beneath the clip (52) inclined towards an inflow direction (42). ### Claim 3 (depends on 1) Wiper blade (10) according to claim 1, characterized in that the covering cap (16) has guide ribs (36) on the one of the opening (34) and the recess and on an outer side facing the wiper arm (18). ### Claim 4 (depends on 1) Wiper blade (10) according to claim 1, characterized in that a spoiler (12) is provided and the covering cap (16) blends on each of its ends with a connecting profile (30) into a profile of the spoiler (12). ### Claim 5 (depends on 1) Wiper blade (10) according to claim 1, characterized in that the wiper arm comprises a wiper rod (18) with a rectangular cross section which, in a mounted position, runs at least partially on an inflow side of the wiper blade (10) and is twisted around its longitudinal axis in such a way that, at least in a region of a spoiler (12), a wide side of the wiper rod (18) runs inclined to an inflow direction (42) and its end (26) is arranged with the wide side parallel to guide ribs (36) on an outer side of the covering cap (16). ### Claim 6 (depends on 1) Wiper blade (10) according to claim 1, wherein a bearing pin (28) has a rivet pin (62) on one end, with which the fastening plate (56) is fastened to the wiper rod (18, 26). ### Claim 7 (depends on 6) Wiper blade (10) according to claim 6, characterized in that the rivet pin (62) is pre-mounted in the fastening plate (56) with a press fit. ### Claim 8 (depends on 1) Wiper blade (10) according to claim 1, characterized in that the connection element (22) has, on its longitudinal sides, edges (64) bent towards the wiper rod (18), which abut an outer contour of an end (26) of the wiper rod (18) with a press fit in a region of its rounded tips (58). ### Claim 9 (depends on 8) Wiper blade (10) according to claim 8, characterized in that a clearance between the edges (64) is less than a width of the end (26) of the wiper rod (18) so that a press fit results when they are joined. ### Claim 10 (depends on 8) Wiper blade (10) according to claim 8, characterized in that a clearance between the edges (64) is greater than a width of the end (26) of the wiper rod (18) so that a press fit is produced by crimping the edges (64). ### Claim 11 (depends on 1) Wiper blade (10) according to claim 1, characterized in that the covering (70) clips into a snap-in hole (68) of the end (26) of the wiper rod (18).
