A mask for aquatic activities, the mask comprising a relatively rigid frame carrying at least one transparent lens, and a flexible skirt joined with a perimeter of the frame. The mask also includes a strap for holding the mask against a user's head and buckles for adjusting the length of the strap. The buckles are joined with lateral sides of the frame by brackets extending from the lateral sides. The brackets are made of a selected flexible material.
A device for releasably connecting a weight pouch to a pocket of a scuba diving jacket. The device comprises a relatively flat sheath connected to and integrally with the diving jacket. A latch member is attached to the weight pouch, the latch member having arms that are elastically deformable in a plane of the sheath and sides tapered relative to a longitudinal plane of symmetry of the sheath to provide snap closure when the latch member is inserted in the sheath. An inward ly-projecting abutment inside the sheath engages ends of the arms when the device is in a closed position, thereby preventing the latch member from sliding out of the sheath. A member is provided for bending the arms of the latch member so as to release them from a position such that they meet the abutment and enable the device to be opened. The bending member includes a cap slidingly mounted on the latch member and contains tapered projections for engaging the tapered sides of the arms. Upon movement of the cap relative to the latch member that induces elastic deformation of the arms, the tapered projections release the ends of the arms from the abutment in the sheath. The cap and the latch member are preferably connected to the same handle for inducing their relative movement by respective flexible connection elements. The element connecting the handle to the latch member is longer than that connecting the handle to the cap, so that the tensile force exerted on the handle first causes relative movement of the cap with respect to the latch member inside the sheath.
A swimming fin comprising a blade extending from a shoe open at its rear side, and a rear heel strap connected to the sides of the shoe by at least one buckle, the buckle having a base plate integral with the shoe. A buckle arm is joined with connected to the strap so as to allow adjustment of the strap's tension, an intermediate lever being connected pivotally to the base plate and the arm. A reversible attachment member is also provided for connecting the intermediate lever to the base plate to achieve closure of the buckle. Between the intermediate lever and the base plate, a disengageable articulation member is provided for reciprocal engagement between them, a pivotal connection, and, at the same time, for allowing their separation in a direction opposite that of tensioning the strap. In this manner, the intermediate lever may be separated from the base plate following release of the attachment member, and disconnection of the disengageable articulation member.
