An antislip insert (1) with a trapezoid outline and a rough external surface is adapted to be seated on a recess of a fixing moulding. To secure this insert against falling out of the moulding it is suggested that the moulding comprises a lengthwise groove (2) on its lower side, said groove being finished with a widening (3), preferably with a triangle profile, and said groove (2) being adapted to be seated on a protrusion extending from the recess of the fixing moulding, wherein said protrusion of the fixing moulding has a widening that corresponds with the shape of the groove (2) in the insert (1). In preferred embodiments, the insert comprises protrusions (7) and/or symmetrical shoulders (8) and the fixing moulding comprises channels with a corresponding shape for receiving said protrusions or shoulders. |
