ABSTRACT:
A guide for protecting threads and seals when joining lengths of production tubing has a guiding portion made of two semicyclindrical polypropylene elements, which when placed together have an annular cross section and form a funnel-like upper end. A strap made of two generally semicircular halves fits within an outer recess on the surfaces of the guiding elements. Abutting edges of the strap halves are constructed with interfitting projections and a central recess for a torsion spring. A hinge pin extends through the projections and the torsion spring. Opposite edges of the strap halves have central recesses to receive a latch. Pins extend axially through the recesses. A latch is pivoted on one pin and engages the other pin when the latch is closed. Handles fit in diametrically opposite circular recesses between the hinge pin and latch pins. The handles are secured by large bolts having heads which engage internal recesses in the guide halves. Each bolt secures one guide half to the handle, locking the strap half therebetween. Worn guide halves are replaced or sizes changed by removing the two bolts, replacing the guide halves with different guide halves and reinserting the bolts.
