Abstract
Abstract A grip sleeve (1) from plastics or the like material, for a handle of a pliers or nippers of the kind which has at least one leaf spring (3) between both its handles for opening the pliers. To localize and retain the spring, the sleeve is formed with an elongate slot (4) on its side facing towards the opposite handle, the slot being open towards the opposite handle and is T-shaped, seen in cross section through the sleeve. At one end, the slot has its cross section, which is suited to the cross-sectional dimensions of the spring, freely exposed for inserting the spring in the crossbar (5) of the T. The stem (6) of the T forms the opening of the slot and the spring is thereby kept in place by flanges (7) on either side of this opening, formed by the T configuration.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
246 words
In combination with a pair of pliers or nippers having a pair of handles and at least one leaf spring disposed between the pair of handles, the spring being positioned adjacent the interior of one of the pair of handles, the spring being arranged to exert a force on the other one of the pair of handles when the pliers are closed, the spring being further arranged to bias the pliers to an open position when a closing force is removed from the handles, the improvement comprising: a grip sleeve mounted on at least said one of the pair of handles, the sleeve having a longitudinally extending side slot positioned in facing relationship to the other of the pair of handles, the slot having a T-shape when seen in cross-section through the sleeve, the leg of the T-shape extending toward the other of the pair of handles and forming the opening in the slot, the crossbar of the T-shape having its cross-sectional dimensions suited to the cross-sectional dimensions of the leaf spring, one end of the slot being freely exposed to permit insertion of the leaf spring in the crossbar, the leg and the crossbar of the T-shape forming a pair of flanges in the sleeve on opposed sides of the opening in the slot, one end of the leaf spring being received in said one end of the slot, said one end of the leaf spring being retained in position by the pair of flanges.

Claim 3
Dependent Claim
13 words
The combination of claim 1 in which the sleeve is a plastic sleeve.
Claim 4
Dependent Claim
22 words
The combination of claim 1, in which the leaf spring and the slot have constant cross-sections along coacting portions of their lengths.
Claim 5
Dependent Claim
40 words
The combination of claim 1, in which the leaf spring has a decreasing cross-section towards said one end thereof and the slot has a decreasing cross-section towards its said one end for coaction with said one end of the spring.
Claim 6
Dependent Claim
62 words
The combination of claim 1, in which the leg of the T-shape extends past the portion of the slot formed by the crossbar towards the other end of the slot remote from its said one end, whereby the leg of the T-shape affords seating for a tool behind said one end of the leaf spring for removing the latter from the slot.
Claim 7
Dependent Claim
108 words
The combination of claim 1, in which when the one end of the leaf spring is not inserted in the one end of the slot, the crossbar of the T-shape has a depth at its extremities corresponding to the maximum dimension of the thickness of the leaf spring at a corresponding place, the crossbar having a depth inwardly of its extremities at the free ends of the flanges less than the thickness of the leaf spring at said corresponding place, whereby the flanges are elastically deformed and grip the leaf spring when said one end of the leaf spring is inserted in said one end of the slot.
