Abstract

Abstract This tool, notably in the case of an ice ax comprising a tool head formed with a depending shank and a metal tubular handle of substantially elliptic or oval cross-sectional configuration receiving said shank in its upper portion, comprises between said shank and said tubular handle upper portion a pair of half sockets associated with a wedge member; driving this wedge member between one of said half-sockets and the shank permits of locking the assembly, this locking action being reinforced by two rivets axially spaced along the handle axis and extending at right angles to each other.
