Abstract
A lock pin has a generally tubular shaft having a front end formed with a radially outwardly open aperture. A locking ball is radially displaceable in the aperture between an outer locking position projecting radially outward from the shaft and an inner position recessed in the shaft. An actuating rod coaxially slidable in the shaft between front and rear positions has a rear end projecting from a rod rear end and a front end at the aperture. The rod has a formation engaging the ball in at least one of its front and rear positions and pressing the ball into its outer locking position. A unitary handle has one end fixed to the rear end of the shaft, an opposite end fixed to the rear end of the rod, and an elastically deformable connecting portion extending between the handle ends and urging the rod into its one position.
