Coupling Device For A Joining System With An Automatic Safety Lock Mechanism

A coupling device for connection to a feeder designed to transport fasteners from a first element to a second element, the coupling device comprising:

• a coupling body with a feed channel that passes through the coupling body in its longitudinal direction and extends between a first end and a second end of the coupling body;
• a locking element that is mounted in the coupling device with a bearing element so as to be rotatable about a pivot axis, wherein the locking element is movable between a locking position and an open position;
• and
• an elastic element that biases the locking element into the locking position, wherein the locking element comprises a first lever arm and a second lever arm which each extend from the pivot axis to a free end of the locking element, wherein the first lever arm comprises an abutment surface at its free end and wherein the elastic element is in operative contact with the first lever arm of the locking element, so that the abutment surface of the first lever arm projects into the feed channel.
