Abstract: An elongated wand member is provided including a first handle end and a second end from which an annular frame is supported with its medial plane inclined generally 45.degree. relative to the longitudinal extent of the wand member. The end of the wand member adjacent the frame includes a transverse guide eye and the side of the frame remote from the wand member includes a second guide eye. The longitudinal mid-portion of an elongated, flexible and elastic tension member is received through the second guide eye and extends in opposite directions therefrom about the outer periphery of the frame and thereafter through the first wand member supported guide eye.

Abstract: A lock mechanism comprising a mounting part, a manually operable part, a retaining part and a stabilizer part, said parts being pivotally connected together as a substantially parallelogram linkage with the retaining part and mounting part located on opposed sides of such linkage; the manually operable part, retaining part and stabilizer part of the linkage being pivotable relative to the mounting part between a locking condition, in which the retaining part is intended to engage a component which is to be secured by the mechanism and further in which the operable part is substantially parallel with and lies adjacent to the mounting part, and a release condition, in which the retaining part is intended to be disengaged from said securable component; pivotal movement of the linkage between its locking and release conditions being effected by manual displacement of the operable part relative to the mounting part.
