Abstract
Abstract Metallic crimping clips for joining together first and second insulated wires, each clip trough-shaped and having formed therein a series of integral strips and tangs so shaped that, on compressing a clip about the wires, the strips and tangs engage with the wires to form an electrically and mechanically permanent joint between the wires, the joint being capable of slight elastic movement under pressure.

Claim 1
Independent Claim
117 words
A crimping clip comprising a generally trough-shaped, electrically-conductive member having a base and first and second upstanding sidewalls, the base containing a plurality of transverse slits defining a series of cross-strips, alternate cross-strips each being subdivided by a slit substantially perpendicular to the said transverse slit to form a pair of tongue portions bent to lie adjacent to and to extend from the base in the same general direction as the first and second upstanding sidewalls respectively, the transverse edges of the other cross-strips, apart from those edges defining the ends of the base being bent upwardly to form a deflectable lip, the said other cross-strips being pierced at a number of places to provide upstanding tangs.
