A brake for a cable or similar, comprising a first abutment member (40) and a second abutment member (50; 50') which are arranged with an intermediate space for at least a portion of the elongate element. A wedge (30; 30') is arranged in the space and movable between a first position, where the cable (4) is allowed to move in the space, and a second position, where the wedge (30; 30') is forcing the cable (4) against at least a portion of the first abutment member (40), whereby movement of the elongate element is retarded or prevented.

An injector head for feeding a tool string support member downhole is described. The injector head comprises a first gripping device and a second gripping device. The first and second gripping devices are adapted to grip a tool string support member passing through an injector head passageway. The injector head further comprises an actuator movable between a first position and a second position wherein, movement of the actuator between the first and second positions moves at least a portion of both of the first and second gripping devices towards or away from a passageway longitudinal axis.
An apparatus for gripping a support member is described. The apparatus comprises a tubular clamp, the tubular clamp defining a throughbore adapted to receive a support member therethrough, a first apparatus member adapted to engage a first portion of an external surface of the tubular clamp, and a second apparatus member adapted to engage a second portion of the external surface of the tubular clamp. Relative movement of the first apparatus member with respect to the tubular damp in a first direction results in a deflection of a section of a first end of the tubular clamp into the clamp throughbore and relative movement of the second apparatus member in a second direction, opposite the first direction, with respect to the tubular clamp results in a deflection of a section of a second end of the tubular clamp into the clamp throughbore.
A bend restrictor for an elongate flexible element, such as a cable, comprising at least two guide elements (2) and a link element (6), each said guide element (2) comprising spherical portions (10) for coupling to respective spherical portions (14) in said link element (6) in a manner allowing angular movement between the respective guide elements (2) and between the link element (6). The bend restrictor comprises first stop means (11a, 11b) on each guide element (2), for abutment against respective second stop means (18) on the link element (6).
