The 73092-2 from Pomona is a DIY stackable red colour 4mm banana plug with quick wire attachment. Attaches wires quickly with the push-button tab for easy assembly or test lead repair. No soldering or set screws required. User can simply, push and hold the push tab, insert the stripped test lead wire (strip 4mm to 6mm of insulation) and release the push tab to secure the wire down. Great in low voltage applications where prototyping and quick wire attachments are required.
