Abstract: By providing at least two elongated, telescopically engaged tube members which incorporate therein a spring biased, dual locking pin structure in combination with tube aligning and centralizing zones, a unique, adjustable handle and arm assembly is achieved which is capable of being easily moved into a plurality of alternate positions and securely engaged in each position, with unwanted dislodgement or lateral wobbling or movement being completely eliminated. In the preferred embodiment, the elongated telescopically engaged tube members are constructed with cooperating enlarged diameter zones and reduced diameter zones to prevent the unwanted disengagement of the tube members. In addition a plurality of alternate operative end units can be quickly and easily mounted to said elongated handle and arm assembly, with one of said end units comprising a unique mooring clasp and book hook construction.
