The invention claimed is: 1. Loop (19) for attaching a hook secured to a harness or a strap supported by an operator to a portable, elongated, engine powered tool, said loop (19) being secured to the tool in such a way that it said loop (19) is allowed to pivot around an axis oriented substantially
The invention claimed is: 1. Loop (19) for attaching a hook secured to a harness or a strap supported by an operator to a portable, elongated, engine powered tool, said loop (19) being secured to the tool in such a way that it said loop (19) is allowed to pivot around an axis oriented substantially parallel to a longitudinal axis of the tool, characterized in that the loop (19)is allowed to pivot within a predetermined range that is wider in a first direction than in an opposite second direction with respect to an upright position of the loop (19) in relation to a vertical plane through the longitudinal axis of the tool when the tool is in a normal position, characterized in that the loop (19) comprises a pivotal end that is pivotally secured to the tool by a device (13) having a lower section (16) adapted to receive the pivotal end, and further characterized in that the loop (19) comprises a protruding section (23) adjacent the pivotal end that is adapted to abut a portion of the lower section (16) to define the predetermined range with respect to the second direction. 2. Loop (19) for attaching a hook secured to a harness or a strap supported by an operator to a portable, elongated, engine powered tool, said loop (19) being secured to the tool in such a way that it said loop (19) is allowed to pivot around an axis oriented substantially parallel to a longitudinal axis of the tool, characterized in that the loop (19) is allowed to pivot within a predetermined range that is wider in a first direction than in an opposite second direction with respect to an upright position of the loop (19) in relation to a vertical plane through the longitudinal axis of the tool when the tool is in a normal position, characterized in that the loop (19) comprises a pivotal end that is pivotally secured to the tool by a device (13) having a lower section (16) adapted to receive the pivotal end, and further characterized in that the lower section (16) includes a spring (20) adapted to engage a portion of the pivotal end to resiliently bias the loop (19) towards the upright position. 3. Loop according to claims 1 or 2, characterized in that the loop (19) includes an opening that is oriented substantially transverse to said longitudinal axis of the tool, and further characterized in that the opening is adapted to receive a hook secured to a harness or a strap supported by an operator. 4. Loop according to claims 1 or 2, characterized in that the loop (19) is allowed to pivot between the upright position and a position 45° outwards in relation to a normal position of the tool arranged adjacent to an operators hip. 5. Loop according to claims 1 or 2, characterized in that the loop (19) is secured to the tool by the device (13) placed close to a centre of gravity for the tool. 6. Loop according to claims 1 or 2, characterized in that the device (13) comprises a covering section (21), and a strap (14), wherein a tension in the strap (14) secures the device (13) to the tool, and further characterized in that the loop (19) is selectively movable along the longitudinal axis of the tool when the tension in the strap (14) that secures the device (13) to the tool is released. 7. Loop according to claim 6, characterized in that the covering section (21) is coupled to the lower section (16) and maintains a location of the loop (19) with respect to the rower section (16). 8. Loop according to claim 6, characterized in that the lower section (16) is adapted to receive a portion of the loop (19), and further characterized in that the portion of the loop (19) that is received by the lower section (16) is shaped so that the loop in combination with the lower section (16) is only allowed to pivot within the predetermined range. 9. An apparatus for attaching a harness or a strap supported by an operator to a portable, elongated, engine powered tool, said apparatus comprising: a loop (19) having a pivotal end and an opening that is oriented substantially transverse to a longitudinal axis of the tool; a lower section (16) having a recess for receiving the pivotal end of the loop (19); and a covering section (21) coupled to the lower section (16) to maintain the pivotal end of the loop (19) within the recess of the lower section (16), characterized in that the loop (19) is allowed to pivot with respect to the lower section (16) about a pivot axis oriented substantially parallel to the longitudinal axis of the tool, and further characterized in that the loop (19) is allowed to pivot about the pivot axis, with respect to an upright position of the loop (19) towards a first direction within a first predetermined range and towards a second direction within a second predetermined range, the first predetermined range being greater than the second predetermined range, characterized in that the loop (19) comprises a protruding section (23) adjacent the pivotal end that is adapted to abut a portion of the lower section (16) to define the second predetermined range. 10. An apparatus for attaching a harness or a strap supported by an operator to a portable, elongated, engine powered tool, said apparatus comprising: a loop (19) having a pivotal end and an opening that is oriented substantially transverse to a longitudinal axis of the tool; a lower section (16) having a recess for receiving the pivotal end of the loop (19); and a covering section (21) coupled to the lower section (16) to maintain the pivotal end of the loop (19) within the recess of the lower section (16), characterized in that the loop (19) is allowed to pivot with respect to the lower section (16) about a pivot axis oriented substantially parallel to the longitudinal axis of the tool, and further characterized in that the loop (19) is allowed to pivot about the pivot axis, with respect to an upright position of the loop (19), towards a first direction within a first predetermined range and towards a second direction within a second predetermined range, the first predetermined range being greater than the second predetermined range, characterized in that the lower section (16) includes a spring (20) adapted to engage a portion of the pivotal end to resiliently bias the loop (19) towards the upright position. 11. The apparatus according to claim 10, characterized in that the covering section (21) is adapted to bias the spring (20) towards the pivotal end of the loop (19). 12. The apparatus according to claims 9 or 10, characterized in that the second predetermined range is defined between the upright position and a position approximately 45° outwards of the upright position. 13. The apparatus according to claims 9 or 10, further comprising a strap (14) adapted to secure the loop (19), the lower section (16) and the covering section (21) to the tool via tension in the strap (14), characterized in that the loop (19) is selectively movable along the longitudinal axis of the tool when the tension in the strap (14) is released.
