Title:
LOCKING MECHANISM FOR TUBULAR BODY
Document Type and Number:
WIPO Patent Application WO/2017/199718
Kind Code:
A1
Abstract:
In the present invention, a locking member is attached so as to be movable in a radially outward direction with respect to a housing by means of a tapered section of a tubular body when the tubular body is inserted therein. The housing is provided with slits through which bent sections provided at tip ends of the locking member and curved in a radially inward direction pass and that are formed to be engaged with engagement sections of the tubular body mounted on the housing. Gaps are provided between the bent sections and ends of the slits, the ends being located at sides in the opposite direction from the tip ends of the locking member, so as to prevent contact therebetween at least during movement of the locking member.
