ABSTRACT:
A device is provided for locking a front end of a spear shaft in a spear gun. The device comprises a bridge extending crosswise over a distal end of the gun with a substantially U-shaped nosepiece joined to the distal end and revolving relatively freely about a crosswise axis thereof. The nosepiece includes at least two arms connected to respective ends of a relatively elastic cable that may be tensioned against a rear end of the shaft, when the shaft is placed on a support surface along the body of the gun. The bridge is attached to and integrally with the ends of the elastic cable and is located a selected distance from the support surface such that the shaft is retained against the surface when the spear is in a stowed or loaded position.
