Abstract

A holding wrench (6) for holding drill string components (2') and including positioning means (10) for moving at least two gripping means (9) into engagement with wrenching surfaces (20) of the drill string components, wherein the gripping means are pivotal in a plane perpendicular to a central axis of the drill string between an active, gripping position and an inactive, retracted position. The wrench is distinguished by each gripping means (9) including locking means (14) for interlocking engagement with engagement means (15) on an adjacent gripping means (9) in the active position so as to obtain a closed rigid wrench structure.
