The hydrophone housing farther includes a first portion and a second portion. One of the portions has a receiving recess, The hydrophone cap installs on this receiving recess. The portions each include a contact surface which contacts the cable when the portions fasten around the cable. The portions clamp around the cable via screws, The contact surface includes raised bosses which securely grip the cable by increasing contact pressure per unit area in a region of contact between the raised bosses and the cable. In another feature, the portion which contains a receiving recess further includes a wire-clearance recess and a wire passageway, between the receiving recess and the wire-clearance recess. In another feature, an outer cylindrical surface of each hydrophone cap is flush with an outer cylindrical surface of each hydrophone housing.
