A cable clasp comprises a tail including an engagement face. The cable clasp further comprises a head including a handle that connects to the tail and defines a mouth opening into which the tail is movable. The cable clasp is biased towards a closed-loop position in which at least a portion of the tail is disposed in the mouth opening. The head further includes a lock having a catch engageable with the engagement face in a lock position to: 1) prevent motion of the tail relative to the head in a first direction, and 2) permit motion of the tail relative to the head in a second direction opposite the first direction by sliding the catch over the engagement face. The catch and the engagement face are also disengageable in a release position to permit motion of the tail relative to the head in both the first and second directions.

a handle including a distal hinge end pivotally connected to the distal hinge end of the tail, the handle defining a proximal mouth opening and distal mouth opening together providing a passageway into which the tail is movable to permit the clasp to move from an open-loop position to a closed-loop position and vice versa, in the open-loop position the free proximal end of the tail being spaced from the passageway, in the closed-loop position at least a portion of the free proximal end being disposed within the passageway, and the free proximal end of the tail passing through the proximal mouth opening to enter the passageway when moving from the open-loop position to the closed-loop position, the handle including:
a neck;
a grip connected to the neck opposite the distal hinge end of the handle, the grip including a first grip arm extending generally perpendicularly relative to a loop plane in which the tail moves relative to the handle and a second grip arm extending generally perpendicularly relative to the loop plane, and the first and second grip arms being disposed on opposite sides of the neck; and
a lock connected to the handle and protruding from the proximal mouth opening, the lock including a catch engageable with the engagement face of the tail, the catch and the engagement face being engageable in a lock position to:

2) permit motion of the tail relative to the head in a second direction opposite the first direction by sliding the catch over the engagement face, and
the lock and the engagement face being disengageable in a release position to permit motion of the tail relative to the head in both the first and second directions.

4. The cable clasp of claim 1 , further comprising a first elastic element connected to the tail and the head biasing the clasp towards the closed-loop position.
5. The cable clasp of claim 1 , wherein the lock has a T-shape including:
a first leg pivotally connected to the handle within the passageway;
a second leg including the catch; and
a third leg including a release button being manipulable to pivot the lock relative to the handle.
6. The cable clasp of claim 5 , further comprising a compression spring compressed between the handle and the first leg of the lock to bias the catch into engagement with the engagement face of the tail.
7. The cable clasp of claim 6 , wherein the compression spring applies a force to the lock along a line of action, and the line of action extends through a portion of the loop plane enclosed together by the tail and the handle.
8. A method of manufacturing a cable clasp, comprising the steps of:
providing a tail including a free proximal end having an engagement face, the tail further including a distal hinge end opposite the free proximal end, the distal hinge end including a hinge face having a first torsion spring hole extending generally perpendicularly relative to a loop plane;
providing a head defining a mouth opening into which the free proximal end of the tail is pivotable, the head including a distal hinge end spaced apart from the mouth opening, the distal hinge end of the head including a hinge face having a second torsion spring hole extending generally perpendicularly relative to the loop plane;
engaging a torsion spring with one of the tail and the head by positioning a first leg of the torsion spring within the torsion spring hole of the one of the tail and the head; and
engaging the other of the tail and the head with the torsion spring by positioning the hinge face of the other of the tail and the head proximate the torsion spring and pivoting the tail relative to the head in the loop plane such that the cable clasp moves towards a closed-loop position and a second leg of the torsion spring passes along the hinge face of the other of the tail and the head and then into the torsion spring hole of the other of the tail and the head.
9. The method of manufacturing a cable clasp of claim 8 , wherein the head includes a handle having an elongated grip, a largest dimension of the elongated grip defines a major axis of the handle, the handle and the tail define a loop plane in which the tail pivots relative to the handle, and the major axis is generally perpendicular to the loop plane.
10. The method of manufacturing a cable clasp of claim 8 , wherein the torsion spring biases the clasp towards the closed-loop position after the other of the tail and the head is engaged with the torsion spring.
11. A cable clasp for supporting an article, comprising:
a tail forming part of a loop and including a free proximal end having an engagement face, and the tail including a distal hinge end opposite the free proximal end;
a head forming another part of the loop, the head including:
a handle including a distal hinge end pivotally connected to the distal hinge end of the tail, the handle defining a proximal mouth opening and a distal mouth opening providing a passageway into which the tail is movable to permit the clasp to move from an open-loop position to a closed-loop position and vice versa, in the open-loop position the free proximal end of the tail being spaced from the passageway, in the closed-loop position at least a portion of the free proximal end being disposed within the passageway, and the free proximal end of the tail passing through the proximal mouth opening to enter the passageway when moving from the open-loop position to the closed-loop position, the handle including:
a neck;
a grip connected to the neck opposite the distal hinge end of the handle, the grip including a first grip arm extending generally perpendicularly relative to a loop plane in which the tail moves relative to the handle and a second grip arm extending generally perpendicularly relative to the loop plane, and the first and second grip arms being disposed on opposite sides of the neck; and
