Clamp means for joining objects together

A clamp means, preferably with a profile-shaped design, for joining together two objects in a fast and simple snap-on manner, comprising a male part and a female part provided respectively for each object, said female part comprising at least one springy, barb-like profile element attached along the upper edge of the female part, and in such a manner that for providing a retaining effect for the male part when the male part is inserted into the female part cavity, said profile element extending down into said cavity and being adapted to yield elastically sideways when the male part is inserted in the cavity and engages a profile element surface, and thereafter to be relaxed and return quickly to a less strained position when the tip of the male part has passed by the profile element, said male part tip having such dimensions that said tip is retained by the profile element due to a barb effect and against the cavity bottom due to an engagement effect, a further clamping effect also being obtained due to a pinch effect between the profile elements or between the single profile element and the opposite wall, said profile element being convexly curved when viewed in the insertion direction, that the lower edge of said profile element is located substantially closer to the cavity bottom than to the upper edge of the wall, a male part section behind said male part tip having a surface with a substantially complementary cross section shape in relation to said profile element surface when the profile element is in its less strained position, in order to obtain a firm and rigid engagement.
