Hose clamp pliers
A hose clamp pliers for use with both a wire spring hose clamp and a band spring hose clamp is disclosed. Two arms of the hose clamp pliers each rotatably carry contact points of different configurations. The first contact point is designed to receive, in a first position, an end portion of a wire spring clamp through a notch; and in a second position, to receive a hoop-shaped end of a band spring clamp. The second contact point is configured to receive both an end portion of a wire spring clamp, and a tab-shaped end of a band spring clamp. The hose clamp pliers is provided with a thumb release cooperating with a ratcheting pawl to control opening and closing of the pliers arms, which opens and closes the hose clamp.
