An elastic cord member and connector arrangement includes a connector having a coupling hole and two opposite notches at two opposite sides of said coupling hole and two opposite notches at two opposite sides of said coupling hole, an elastic cord member, and a coupling hole and two opposite notches at two opposite side of said coupling hole, an elastic cord member, and a coupling socket fixedly secured to one end of the elastic cord member and detachably coupled to the coupling hole of the connector by way of a spring supporting one end on the inside of the coupling hole of the connector, and by way of two locating lugs raised from the periphery at two opposite sides and adapted for inserting into notches of the coupling hole of the connector. The connector has two L-shaped locating holes vertically spaced at two opposite sides and arranged in reversed directions and respectively disposed in communication with the notches of the coupling hole of the connector. Each of the L-shaped locating holes has a length extending over the corresponding notch of the coupling hole, a depth extending over the bottom side of the corresponding notch of the coupling hole, and a width longer than the depth of the locating lugs of the coupling socket, so that the locating lugs of said coupling socket can be forced into engagement with the L-shaped locating holes by turning the coupling socket in the coupling hole of the connector.

A connector assembly for elastic cord members comprising: (a) at least one connector member having at least one coupling hole with a notch disposed at each of two opposite sides of said coupling hole, said connector member having two L-shaped locating holes arranged in opposite directions from each

A connector assembly for elastic cord members comprising: (a) at least one connector member having at least one coupling hole with a notch disposed at each of two opposite sides of said coupling hole, said connector member having two L-shaped locating holes arranged in opposite directions from each other, each L-shaped locating hole in communication with one of said notches, each of said L-shaped locating holes having an outer end and an inner end and a front side; (b) at least one elastic cord member; and (c) at least one hollow substantially cylindrical coupling socket secured to said elastic cord member configured to be rotatably received in said at least one coupling hole, said coupling socket having a spring disposed so as to bear against a portion of said connector member when said at least one coupling member is inserted into said at least one coupling hole, said coupling socket having two locating lugs extending from opposite sides, said two locating lugs configured to pass through said notches when said coupling socket is inserted into said connector member through said coupling hole; wherein inserting said coupling socket into said coupling hole causes each of said lugs to enter into said outer end of one of said L-shaped locating holes, such that rotation of said at least one coupling socket relative to the at least one connector causes each of said each locating lugs to reach said inner end of one of said L-shaped locating holes such that said spring urges said lugs against said front sides of each of said L-shaped locating holes to secure said coupling socket to said connector member.
