ABSTRACT:
A crimping tool includes a pair of arm members and a driving mechanism such as a pair of handles for moving the arm members. An elongated working jaw is mounted on each of the arm members, one of the working jaws having a female die and the other working jaw having a male die arranged thereon. The female die has a notch, and the male die has a base part and an elongated leading face spaced from the base part. A locking mechanism prevents the driving mechanism from returning to an open position before the driving mechanism is brought to a fully closed position. A resilient elastomeric block is provided in the tool to enable the driving mechanism to be brought to the closed position when an article to be crimped is located between the working jaws.
