Abstract

A two-piece handle assembly (10, 10a) including a plunger (12, 12a) and a body (24, 24a) having an axial bore (50, 50a) in which plunger (12, 12a) can move between retracted and extended positions. The upper end (28) of body (24, 24a) includes a pair of opposed longitudinal slots (32) that permit radially outward resilient movement of the upper end (28) to enlarge a bore (52), defined by a neck portion (54) of the body, to permit insertion of plunger (12) into body (24, 24a). A plunger shoulder (44) is designed to engage a body shoulder (55) to limit movement of the plunger in the direction of retraction, and a finger pad (13) is provided to limit movement of the plunger in the direction of extension.
