The invention provides a walking aid having a tubular shaft comprising two tubular shaft portions S2, S3 joined end to end by a connector (C figure 1); the connector comprising a pair of connector elements 2,4, each connector element having a spigot portion 6,14 for securing inside an open end of one of the two tubular shaft portions; the connector elements 2,4 being provided with means (e.g. threaded screw connection) enabling them to be releasably fastened together. The connector elements 2,4 may have opposing flanges 16,8 and a sealing element 24. Another embodiment is also described (figures 9-12) wherein the connectors have formations which align when connected and a locking element which engages said formations and prevents relative rotation of the two connector elements. |
