Abstract
A clamp for an oil well line is disclosed, the clamp having a casing, typically a pair of wedge members defining a line receiving recess between them and wherein the wedge member are movable within a channel in the casing to move together and grip the line when axial force is applied to the line. The radially outermost faces of the wedge members are typically shaped to match the taper of the channel in the casing, and so are pressed together as they move axially down the tapered channel. One wall of the channel is typically movable to disengage from the wedge member when the gripping force is to be removed. The line-receiving recess can be in the form of an arc or a dog leg, and can be lined with a high friction material or a softer material to minimize damage to the line by the clamping force.
