20Pcs Wire Connectors, Double-wire Push-in Connector with Locking Buckle, 2 Pin 2 Way Peel-free Universal Compact Wire Terminals for Cable, Toolless Spring Quick Splice Wire Connector for AWG18-22

Brilliant bit of kit

The wires in a 5A cable used on many low power appliances, lighting and similar circuits consisting of two inner insulated wires with an outer sheath will not pass through the small holes in the connector's caps.In particular I wanted them for shortening the cables on some under-cabinet LED lighting from a well known Swedish supplier but they were impossible to fit on the main cables.When it came to the thinner distribution block-to-lights cables, the inner two wires would fit through the holes in the caps, but it was very fiddly to get them to seat properly in the two channels in the body and when the cap was closed only one of the 2 IDCs (Insulation Displacement Connector) made contact.So a total fail. I'm going to have to resort to soldering and heat shrink tubing.

Useless. Doesn’t hold, holes too small, just crap. Sent back straight away.

Not impressed. Even used on the smallest of gauge wire fails to make a secure SAFE joint. Do not try and reuse, as stated because the material used for the cover will break. Waste of time and money. Resorted to soldering joints, insulating with heat shrink.

Expensive & only for low voltage use
