A fastening means is for attaching a cable to a tubular body. The tubular body has a sleeve with a first end face and a second end face. The fastening means has a first attachment part arranged with a first abutment surface for resting against the first end face; a second attachment part arranged with a second abutment surface for resting against the second end face; both the first attachment part and the second attachment part including a through cable recess; and a tightening device for pulling the first attachment part and the second attachment part towards each other. The fastening means is characterized by the first attachment part and the second attachment part being adjustably connected in a spaced-apart manner via the tightening device.

Pressure sensing device and method for using the same
A pressure-sensing device is for use in an underground well. The pressure-sensing device includes a pressure sensor arranged at least to sense whether a pressure in the well is below or above a given limit value, and a signal generator arranged to generate an acoustic signal in a well body in the well in response to a sensed pressure from the pressure sensor exceeding said limit value. A method is for measuring pressure in an underground well. A use of a pressure-sensing device is to monitor the pressure between two spaced-apart barrier elements in an underground well.

A pressure-sensing device (1) for use in an underground well (2) is described, characterized by the pressure-sensing device (1) including : - a pressure sensor (13, 13') arranged at least to sense whether a pressure in the well (2) is below or above a given limit value; and - a signal generator (15, 15') arranged to generate an acoustic signal in a well body (12) in the well (2) in response to a sensed pressure from the pressure sensor (13, 13') exceeding said limit value. A method of measuring pressure in an underground well (2) and, finally, a use of a pressure-sensing device (1) to monitor the pressure between two spaced-apart barrier elements (23, 25) in an underground well (2) are described as well.

CLEANING MAGNET DEVICE FOR CLEANING DRILLING FLUID
A cleaning magnet device (1a-1c) for cleaning drilling fluid, the cleaning magnet (1a-1c) being disposed in a liquid flow, and the cleaning magnet (1a-1c) being provided with a removable material (6) which is arranged to prevent magnetic bodies from accumulating directly on the cleaning magnet (1a-1c). The cleaning magnet (1b) is surrounded by a closed stocking (8) which is provided, at its open portion, with a weight mass (10) in the form of a non-magnetic metal ring. Upon lifting the stocking away from the magnet (1a) by means of a lifting tool (12), the material (6) is rolled off the magnet whereby magnetic bodies, which have been attracted to the magnet from the drilling fluid, will remain in the stocking (8) as the stocking (8) is being moved up.
A cleaning tool (1) for use in a borehole where the cleaning tool (1) comprises a collection volume (58), and where an actuator (25) in the cleaning tool (1) is disposed to be able to reduce a flushing liquid volume (56) being in the cleaning tool, as a discharging flushing liquid from the flushing liquid volume (56) is led through a jet pod (46) and directed towards an object to be cleaned.
