Or relating to connecting devices

1. An attaching arrangement for attaching a connecting device to a first article, the attaching arrangement comprising:

an attaching member receivable through an opening in the first article; and

a locking arrangement comprising a detent formation, wherein the detent formation comprises a resilient member, the resilient member being receivable in said opening in the first article to lock the connecting device to the first article, and the resilient member being substantially V shaped, having opposite arms forming the V;

wherein the locking arrangement further includes a mounting member defining an aperture, the mounting member being attached to one of the arms;

wherein the attaching arrangement has a fastening element extending through the aperture; and

wherein the locking arrangement further includes a release tab attached to the other of said arms to facilitate moving the arms towards each other;

wherein the attaching member comprises a first projecting portion for engaging the first article and a second projecting portion for insertion through the first article;

wherein the attaching arrangement is rotatable relative to the first article to an attaching position to attach the connecting device to the first article, whereby when the attaching arrangement is so rotated, a region of the first article can be received between the first and second projecting portions;

wherein the second projecting portion has a leading surface, the leading surface being the first region of the second projecting portion to pass over the aforesaid region of the first article when the attaching arrangement is rotated to the attaching position, and wherein the second projecting portion has an attaching surface to engage the first article when the attaching arrangement is in the attaching position;

wherein the attaching member further includes a spacer portion extending between the first and second projecting portions, and a gap is defined between the first and second projecting portions, the gap being larger at the leading surface than at the attaching surface, the leading surface converging toward the attaching surface.

2. An attaching arrangement according to claim 1 , wherein the arms are resiliently deformable away from, and towards, each other, wherein the arm attached to the mounting member is movable from a resiliently deformed position to a non-deformed position when the attaching arrangement is moved to an attaching position, the movement of said arm from the deformed position to a non-deformed position being a movement of the resilient member from a deformed position to a non-deformed position.

3. An attaching arrangement according to claim 1 , wherein the fastening element extends from the first projecting portion to fasten the attaching arrangement to a securing arrangement.

4. An attaching arrangement according to claim 3 , wherein the fastening element is threaded to threadably cooperate with corresponding threads on the securing arrangement.

5. An attaching arrangement according to claim 1 , wherein the first projecting portion engages a first face of said region of the first article, and the second projecting portion engages an opposite second face of said region of the first article.

6. An attaching arrangement according to claim 1 , wherein the first and second projecting portions extend outwardly from the fastening element, the second projecting portion extending from the spacer portion in opposite directions relative thereto.

7. An attaching arrangement according to claim 6 , wherein the first projecting portion extends radially from the fastening element and is substantially circular, and wherein the second projecting portion is substantially rectangular having a width greater than its length.

8. An attaching arrangement according to claim 1 , wherein the second projecting portion extends across the first projecting portion.

9. An attaching arrangement according to claim 1 , wherein the spacer portion has a stop formation to prevent rotation of the attaching arrangement in one direction, the stop formation comprising diagonally opposite regions of the spacer portion, the distance between said regions being greater than the width of the opening.

10. An attaching arrangement according to claim 9 , wherein the stop formation comprises a region of the spacer portion configured to engage the first article when the attaching arrangement is rotated in the aforesaid direction.

11. An attaching arrangement according to claim 1 , wherein the spacer portion has a curved edge to allow rotating of the attaching arrangement relative to the first article, and the spacer portion has diametrically opposed curved edges, wherein the diametrical distance between said curved edges is less than the width of the opening in the first article.

12. A connecting device for connecting a first article to an elongate second article, the connecting device comprising:

an attaching arrangement for attaching the connecting device to the first article, the attaching arrangement comprising:

an attaching member receivable through an opening in the first article; and

a locking arrangement comprising a detent formation, wherein the detent formation comprises a resilient member, the resilient member being receivable in said opening in the first article to lock the connecting device to the first article, and the resilient member being substantially V shaped, having opposite arms forming the V;

wherein the locking arrangement further includes a mounting member defining an aperture, the mounting member being attached to one of the arms;

wherein the attaching arrangement has a fastening element extending through the aperture; and

wherein the locking arrangement further includes a release tab attached to the other of said arms to facilitate moving the arms towards each other;

a securing arrangement for securing the connecting device to the elongate second article, the securing arrangement being fastened to the attaching arrangement by the fastening element.

13. A connecting arrangement comprising a connecting device and a first article, the connecting device comprising:

an attaching arrangement for attaching the connecting device to the first article, the attaching arrangement comprising:

an attaching member receivable through an opening in the first article; and

a locking arrangement comprising a detent formation, wherein the detent formation comprises a resilient member, the resilient member being receivable in said opening in the first article to lock the connecting device to the first article, and the resilient member being substantially V shaped, having opposite arms forming the V;

wherein the locking arrangement further includes a mounting member defining an aperture, the mounting member being attached to one of the arms;

wherein the attaching arrangement has a fastening element extending through the aperture; and

wherein the locking arrangement further includes a release tab attached to the other of said arms to facilitate moving the arms towards each other; and

the connecting arrangement further including a securing arrangement for securing the connecting device to an elongate second article, the securing arrangement being fastened to the attaching arrangement by the fastening element.

14. A connecting arrangement according to claim 13 , comprising a plurality of the connecting devices, which can be attached to the first article.

15. A connecting arrangement according to claim 13 , wherein the first article comprises an elongate support.
