Releasing them merely requires that the user press the orange aluminium press button at the top end of the pin. The pin can then be easily inserted into the existing threaded hole.  
When the press button is released, the threaded segments engage in the thread of the part.
A semi-turn at the end will lock the threaded lock pin firmly and securely in place inside the bore hole.

Releasing the connection merely requires a quarter turn of the threaded lock pin in anti-clockwise direction and a push of the press button.

Affixed to the handle is a nut that is designed to secure a retaining cable / a clip for a retaining cable.
