Abstract

The sleeve or collar (7) is formed from twin opposed convergent lightly angled inner surface land is contracted via a tangent screw (10) arrangement. The usual threaded sleeve (3) junction between the intersliding tubes (1, 6) has a terminal washer plate (4) connecting to the contracting collar (7) by a circumferential slot. The connection will resist tension or compression and the split or circumferential gap in the collar is sized to limit the clamping force. Two splits can be used; the collar can be of uniform internal diameter, varied in curved forms, singularly tapering, grooved to prevent sliding, square for square props, and can be actuated hydraulically.
