Abstract
Improved extensible strut, essentially characterized in that the retention device between both coaxial bodies that comprise it, is constituted by an outer widening of the end of the housing, whose widening presents its conical tapered front, while the wrapped body goes through centrally to a bowl axially displaceable, whose lower concavity is offset from said conical front of the widening of the housing, so that the offset of the bowl on the conical front retains by throttling said coaxial bodies together; while the lower end of the housing is displaceable through a spindle driven by a pedal as a crosshead.
