Abstract : A coupling for joining sections of an underwater towed acoustical array includes male and female couplers. The male coupler has an annular end portion with an axial bore that receives a first towed array section and a first connector and an annular body integral with and extending coaxially from the annular end portion. An outer groove is disposed around an outer circumference of the annular body. The female coupler has an annular end portion and an axial bore that receives a second towed array section and a second connector and a cup-shaped body portion integral with and extending from the annular end portion. The cup-shaped body portion has an inner groove disposed on the inner surface and an aperture through the cup-shaped body portion communicating with the inner groove. The inner groove is located so as to be in registry with the male coupler outer groove when the annular body is inserted into the cup-shaped body portion to form an annular channel. A retaining means in the form of a cord or ball bearings, is inserted through the aperture and into the annular channel to maintain the annular body in fixed position within the cup-shaped body portion.
