Tongs including a pair of elongated arms coupled together to move between a generally compressed configuration and a generally expanded configuration. The tongs further include a locking mechanism having a frame, a lock member and a spring to bias the lock member away from the frame. The lock member being movably coupled to the frame to move between a first position in which the lock member allows movement of the arms to the expanded configuration and a second position in which the lock member prevents movement of the arms beyond an intermediate configuration between the expanded and compressed configurations.
