The invention relates to a releasable structural bond, being well suitable for establishing releasable, so-called momentary connection for structural elements, in particular nodal points of lattice structures, comprising a negative receiving element with at least one aperture and a positive connecting element to be introduced therein. The essential characteristic of the invention lies in that the aperture is foremd by a split having the shape of a multi-pointed star, wherein surfacial ranges between the branches of the slit form resilient diaphragm-parts. The connecting element (2) is formed as any rigid positive element, having been arranged at the end of some tubular element (4) or led in said tubular element, having a cross-sectional profile being in compliance with the shape of the split of the receiving element, i. e. corresponding to the star with optional branches; said connecting element can be introduced into the receiving element, which is kept in a self-locking state by the resilient diaphragm-parts. The releasable structural bond is provided with an opening element (3) with extensions (30) bearing up against the resilient diaphragm-parts of the receiving element by applying external force. |
