ABSTRACT:
A coupling spring pin is provided for use in hollow sections or tubes. The coupling spring pin comprises a base spring element and a bolt connected to the spring element. The spring element is provided with a flange and at least two bent spring tongues. The bolt stands perpendicularly on the flange and the two bent spring tongues extend downwards from the flange. The bolt may be provided with a bolt case in order to securely prevent shearing. The bolt case, in its lower region, may be provided with an annular groove and the bolt case may be peripherally (injection) molded on the base in an injection molding tool, so that the plastic material of the flange may fill out the annular groove, which allows the bolt case to be connected to the spring element in an undetachable and stable manner.
