The work presents experimental investigations of clinch connections of structural wooden elements. The tests were carried out using the MTS Insight 50 kN laboratory testing machine. The influence of changing parameters such as the angle of sharpening γ staples, which values were successively 30° and 60°, and the mutual positioning of the staple legs, which was parallel, divergent and convergent, were investigated. The presented results gave information on which parameters, the connection strength is the highest. Experimental research was also supported by numerical studies in which the phenomenon of destruction of this type of connection was simulated. The built-in numerical model gives the opportunity to examine the connection strength for a larger number of cases of change in the value of the angle γ and the angle of mutual positioning of the staple legs.
