A ski safety device prevents unintentional crossing of skis during skiing. It has a support plate mountable on an upper surface of a ski, and a frame above the support. A bottom wall of the frame faces the upper side of the support and a layer of elastically compressible material, such as plastic foam material, is interposed between them. The bottom wall of the frame is formed with an elongated opening and the upper side of the bottom wall has at opposite sides of the opening respective depressions which extend outwardly away from the opening. A projection extends upwardly from the support through the opening and is formed with two transverse extensions which enter into the respective depressions when the frame is turned relative to the support from a position in which the elongation of the opening is parallel to that of the extensions to another position in which the two directions of elongation are inclined relative to one another, under simultaneous compression of the elastically compressible material. Thus, the frame is readibly detachably secured to the support and thereby to the ski in which the support is mounted.
