A release arrangement for a sailboard footstrap which has a female member (22) and a male member (74). The female member (22) is composed of two identical components (38, 40) which locate together by means of pins (152) locating in apertures Chamfered apertures (48, 148) in resilient arm portions of the female member (22) are adapted to receive and retain frusto-conical bosses (94, 90) on the male member (74). The bosses (94, 90) are located on a portion of the male member (74), the sides of which abut pins (152) when relative rotation of the members (22, 74) about the engaged bosses and apertures (94, 48; 90, 148) occurs, the abutment serving to lever the bosses (94, 90) from the apertures (48, 148) at a predetermined magnitude of force exerted to cause rotation. The male (74) and female (22) members may also disengage at other predetermined magnitudes of forces exerted upon the arrangement in other directions. |
