3 locking anges'may' be reversed, as shown in Figure 9 at 8' and 9'.

In order to allow one wire end at a time to be crimped and locked in secured position in the sleeve I, the locking

iiange elements

8 and 9 or 8 and 9 may be provided as separate short ilangeelements adjacent each end of the sleeve i instead of extending continuously throughout the length thereof. This is shown in Figures ,12 and 13 wherein the short interlocking ange elements are indicated vat '8" and 9". VTo facilitate the ready distortion of one end of the sleeve with respect to the other end during the securement of one wire end, a slot I2 having roundedstressdistributing end portions I3 and I4 may be provided intermediate the ends of ther sleeve as shown in Figures 5, 14 and 15. As shown inV these figures, slot I2 extends transversely through a substantial portion of both the upper and lower flanged portions of the sleeve whereby said flanged portions may be considerably.: flexed independently of the remainderof'the sleeve. Y Another means o'f providingfor ready distortion of one Aend of the sleeveLwith respect to theother end is disclosed in Fig. 6- wherein the intermediate portion of one edge of thesleeve is cut away to formv the shallow curvedV recess I5, which distributes the tensile stressat the edge of the sleeve due to the unbalanced pressure at'one end.

A further `modiiication of the sleeve locking meansl is disclosed in Figures 10 and 11, wherein an inwardly `struck tongue/IIS` cooperates with an opening I1 in the sleevewall in a locking relationship similar tov thatexisting between flanges 8 and 9' in Fig. 9;' -The relationship of the tongue and opening' may be reversedn to cooperate in a manner similar tov flanges 81 and 9 in Fig. 2Y ii desired. Furthermore, the tongue and ,opening structure Ymay be employed in the embodiments of Figs. 5y and'6 instead of the locking anges there disclosed. Y

In Figures 'land-'8 the locking structure ofone half of the sleeves of any one of the embodiments of Figs. 1 to 6 and 9 to 11 maybe employed to secure a wirejend I9 to a terminal l8 As in the former embodiments, the wireend is inserted in the sleeve and the sleeve` is squeezed with ordinary .pliers orlightly tapped .with an ordinary hammer so that Vthe cooperating lock- ,ingY flanges or tongue and `opening locking elements snap into locking position. Inthis position the depending tongue 4 holds the .wire end securely crimped inopening 6. .l A

While certain specic embodiments of thisinvention have been shownrit ,willv be understood that various modications may be'lmade within the spirit of the invention. `'Therefore no limitations upon the invention are intended lother than are imposed by the scope of the appended claims.
