An anti-rotation locking unit includes a support member having a mounting portion, a lock-support portion and first engagement part; a locking member having a bearing portion movably supported by the lock-support portion between a locking position and a release position, a coupling formation, and second engagement part, where in the locking position, the first and second engagement parts are mutually engaged so as to prevent rotation of the locking member with respect to the support member; and a return part mounted operatively between the locking member and the support member for biasing the locking member into the locking position, the first and second engagement parts arranged as abutment parts preventing axial movement of the locking member with respect to the support member beyond the locking position.

[ What is claimed is:] [1.]1. An adjustable rod having:a tubular body provided with an internal threading;a threaded shaft threadingly engaged in said internal threading;a counternut threadingly engaged on said threaded shaft;first engagement means which are integral with said tubular body;an annular locking member having a coupling formation and second engagement means and which is axially movable with respect to said tubular body between a locking position in which said coupling formation is engageable with said counternut thereby to be rotatably fast therewith and in which said first and second engagement means are in mutual engagement, and a release position in which at least one of said coupling formation and said second engagement means are disengaged from said counternut and from said first engagement means respectively;return means biassing said locking member into said locking position.
